Literature Review is Faster and Smarter with MAXQDA

Easily import your literature review data

With a literature review software like MAXQDA, you can easily import bibliographic data from reference management programs for your literature review. MAXQDA can work with all reference management programs that can export their databases in RIS-format which is a standard format for bibliographic information. Like MAXQDA, these reference managers use project files, containing all collected bibliographic information, such as author, title, links to websites, keywords, abstracts, and other information. In addition, you can easily import the corresponding full texts. Upon import, all documents will be automatically pre-coded to facilitate your literature review at a later stage.

Capture your ideas while analyzing your literature

Great ideas will often occur to you while you’re doing your literature review. Using MAXQDA as your literature review software, you can create memos to store your ideas, such as research questions and objectives, or you can use memos for paraphrasing passages into your own words. By attaching memos like post-it notes to text passages, texts, document groups, images, audio/video clips, and of course codes, you can easily retrieve them at a later stage. Particularly useful for literature reviews are free memos written during the course of work from which passages can be copied and inserted into the final text.

Find concepts important to your generated literature review

When generating a literature review you might need to analyze a large amount of text. Luckily MAXQDA as the #1 literature review software offers Text Search tools that allow you to explore your documents without reading or coding them first. Automatically search for keywords (or dictionaries of keywords), such as important concepts for your literature review, and automatically code them with just a few clicks. Document variables that were automatically created during the import of your bibliographic information can be used for searching and retrieving certain text segments. MAXQDA’s powerful Coding Query allows you to analyze the combination of activated codes in different ways.

Aggregate your literature review

When conducting a literature review you can easily get lost. But with MAXQDA as your literature review software, you will never lose track of the bigger picture. Among other tools, MAXQDA’s overview and summary tables are especially useful for aggregating your literature review results. MAXQDA offers overview tables for almost everything, codes, memos, coded segments, links, and so on. With MAXQDA literature review tools you can create compressed summaries of sources that can be effectively compared and represented, and with just one click you can easily export your overview and summary tables and integrate them into your literature review report.

Powerful and easy-to-use literature review tools

Quantitative aspects can also be relevant when conducting a literature review analysis. Using MAXQDA as your literature review software enables you to employ a vast range of procedures for the quantitative evaluation of your material. You can sort sources according to document variables, compare amounts with frequency tables and charts, and much more. Make sure you don’t miss the word frequency tools of MAXQDA’s add-on module for quantitative content analysis. Included are tools for visual text exploration, content analysis, vocabulary analysis, dictionary-based analysis, and more that facilitate the quantitative analysis of terms and their semantic contexts.

Visualize your literature review

As an all-in-one literature review software, MAXQDA offers a variety of visual tools that are tailor-made for qualitative research and literature reviews. Create stunning visualizations to analyze your material. Of course, you can export your visualizations in various formats to enrich your literature review analysis report. Work with word clouds to explore the central themes of a text and key terms that are used, create charts to easily compare the occurrences of concepts and important keywords, or make use of the graphical representation possibilities of MAXMaps, which in particular permit the creation of concept maps. Thanks to the interactive connection between your visualizations with your MAXQDA data, you’ll never lose sight of the big picture.

A literature review analyzes the most current research within a research area. A literature review consists of published studies from many sources:

• Peer-reviewed academic publications
• Full-length books
• University bulletins
• Conference proceedings
• Dissertations and theses

Literature reviews allow researchers to:

• Summarize the state of the research
• Identify unexplored research inquiries
• Recommend practical applications
• Critique currently published research

Literature reviews are either standalone publications or part of a paper as background for an original research project. A literature review, as a section of a more extensive research article, summarizes the current state of the research to justify the primary research described in the paper.

For example, a researcher may have reviewed the literature on a new supplement's health benefits and concluded that more research needs to be conducted on those with a particular condition. This research gap warrants a study examining how this understudied population reacted to the supplement. Researchers need to establish this research gap through a literature review to persuade journal editors and reviewers of the value of their research.

Consider a literature review as a typical research publication presenting a study, its results, and the salient points scholars can infer from the study. The only significant difference with a literature review treats existing literature as the research data to collect and analyze. From that analysis, a literature review can suggest new inquiries to pursue.

Identify a focus

Similar to a typical study, a literature review should have a research question or questions that analysis can answer. This sort of inquiry typically targets a particular phenomenon, population, or even research method to examine how different studies have looked at the same thing differently. A literature review, then, should center the literature collection around that focus.

Collect and analyze the literature

With a focus in mind, a researcher can collect studies that provide relevant information for that focus. They can then analyze the collected studies by finding and identifying patterns or themes that occur frequently. This analysis allows the researcher to point out what the field has frequently explored or, on the other hand, overlooked.

Suggest implications

The literature review allows the researcher to argue a particular point through the evidence provided by the analysis. For example, suppose the analysis makes it apparent that the published research on people's sleep patterns has not adequately explored the connection between sleep and a particular factor (e.g., television-watching habits, indoor air quality). In that case, the researcher can argue that further study can address this research gap.

External requirements aside (e.g., many academic journals have a word limit of 6,000-8,000 words), a literature review as a standalone publication is as long as necessary to allow readers to understand the current state of the field. Even if it is just a section in a larger paper, a literature review is long enough to allow the researcher to justify the study that is the paper's focus.

Note that a literature review needs only to incorporate a representative number of studies relevant to the research inquiry. For term papers in university courses, 10 to 20 references might be appropriate for demonstrating analytical skills. Published literature reviews in peer-reviewed journals might have 40 to 50 references. One of the essential goals of a literature review is to persuade readers that you have analyzed a representative segment of the research you are reviewing.

Researchers can find published research from various online sources:

• Journal websites
• Research databases
• Search engines (Google Scholar, Semantic Scholar)
• Research repositories
• Social networking sites (Academia, ResearchGate)

Many journals make articles freely available under the term "open access," meaning that there are no restrictions to viewing and downloading such articles. Otherwise, collecting research articles from restricted journals usually requires access from an institution such as a university or a library.

Evidence of a rigorous literature review is more important than the word count or the number of articles that undergo data analysis. Especially when writing for a peer-reviewed journal, it is essential to consider how to demonstrate research rigor in your literature review to persuade reviewers of its scholarly value.

Select field-specific journals

The most significant research relevant to your field focuses on a narrow set of journals similar in aims and scope. Consider who the most prominent scholars in your field are and determine which journals publish their research or have them as editors or reviewers. Journals tend to look favorably on systematic reviews that include articles they have published.

Incorporate recent research

Recently published studies have greater value in determining the gaps in the current state of research. Older research is likely to have encountered challenges and critiques that may render their findings outdated or refuted. What counts as recent differs by field; start by looking for research published within the last three years and gradually expand to older research when you need to collect more articles for your review.

Consider the quality of the research

Literature reviews are only as strong as the quality of the studies that the researcher collects. You can judge any particular study by many factors, including:

• the quality of the article's journal
• the article's research rigor
• the timeliness of the research

The critical point here is that you should consider more than just a study's findings or research outputs when including research in your literature review.

Narrow your research focus

Ideally, the articles you collect for your literature review have something in common, such as a research method or research context. For example, if you are conducting a literature review about teaching practices in high school contexts, it is best to narrow your literature search to studies focusing on high school. You should consider expanding your search to junior high school and university contexts only when there are not enough studies that match your focus.

You can create a project in ATLAS.ti for keeping track of your collected literature. ATLAS.ti allows you to view and analyze full text articles and PDF files in a single project. Within projects, you can use document groups to separate studies into different categories for easier and faster analysis.

For example, a researcher with a literature review that examines studies across different countries can create document groups labeled "United Kingdom," "Germany," and "United States," among others. A researcher can also use ATLAS.ti's global filters to narrow analysis to a particular set of studies and gain insights about a smaller set of literature.

ATLAS.ti allows you to search, code, and analyze text documents and PDF files. You can treat a set of research articles like other forms of qualitative data. The codes you apply to your literature collection allow for analysis through many powerful tools in ATLAS.ti:

• Code Co-Occurrence Explorer
• Code Co-Occurrence Table
• Code-Document Table

Other tools in ATLAS.ti employ machine learning to facilitate parts of the coding process for you. Some of our software tools that are effective for analyzing literature include:

• Named Entity Recognition
• Opinion Mining
• Sentiment Analysis

As long as your documents are text documents or text-enable PDF files, ATLAS.ti's automated tools can provide essential assistance in the data analysis process.

5 software tools to support your systematic review processes

By Dr. Mina Kalantar on 19-Jan-2021 13:01:01

Systematic reviews are a reassessment of scholarly literature to facilitate decision making. This methodical approach of re-evaluating evidence was initially applied in healthcare, to set policies, create guidelines and answer medical questions.

Systematic reviews are large, complex projects and, depending on the purpose, they can be quite expensive to conduct. A team of researchers, data analysts and experts from various fields may collaborate to review and examine incredibly large numbers of research articles for evidence synthesis. Depending on the spectrum, systematic reviews often take at least 6 months, and sometimes upwards of 18 months to complete.

The main principles of transparency and reproducibility require a pragmatic approach in the organisation of the required research activities and detailed documentation of the outcomes. As a result, many software tools have been developed to help researchers with some of the tedious tasks required as part of the systematic review process.

hbspt.cta._relativeUrls=true;hbspt.cta.load(97439, 'ccc20645-09e2-4098-838f-091ed1bf1f4e', {"useNewLoader":"true","region":"na1"});

The first generation of these software tools were produced to accommodate and manage collaborations, but gradually developed to help with screening literature and reporting outcomes. Some of these software packages were initially designed for medical and healthcare studies and have specific protocols and customised steps integrated for various types of systematic reviews. However, some are designed for general processing, and by extending the application of the systematic review approach to other fields, they are being increasingly adopted and used in software engineering, health-related nutrition, agriculture, environmental science, social sciences and education.

Software tools

There are various free and subscription-based tools to help with conducting a systematic review. Many of these tools are designed to assist with the key stages of the process, including title and abstract screening, data synthesis, and critical appraisal. Some are designed to facilitate the entire process of review, including protocol development, reporting of the outcomes and help with fast project completion.

As time goes on, more functions are being integrated into such software tools. Technological advancement has allowed for more sophisticated and user-friendly features, including visual graphics for pattern recognition and linking multiple concepts. The idea is to digitalise the cumbersome parts of the process to increase efficiency, thus allowing researchers to focus their time and efforts on assessing the rigorousness and robustness of the research articles.

This article introduces commonly used systematic review tools that are relevant to food research and related disciplines, which can be used in a similar context to the process in healthcare disciplines.

These reviews are based on IFIS' internal research, thus are unbiased and not affiliated with the companies.

This online platform is a core component of the Cochrane toolkit, supporting parts of the systematic review process, including title/abstract and full-text screening, documentation, and reporting.

The Covidence platform enables collaboration of the entire systematic reviews team and is suitable for researchers and students at all levels of experience.

From a user perspective, the interface is intuitive, and the citation screening is directed step-by-step through a well-defined workflow. Imports and exports are straightforward, with easy export options to Excel and CVS.

Access is free for Cochrane authors (a single reviewer), and Cochrane provides a free trial to other researchers in healthcare. Universities can also subscribe on an institutional basis.

Rayyan is a free and open access web-based platform funded by the Qatar Foundation, a non-profit organisation supporting education and community development initiative . Rayyan is used to screen and code literature through a systematic review process.

Unlike Covidence, Rayyan does not follow a standard SR workflow and simply helps with citation screening. It is accessible through a mobile application with compatibility for offline screening. The web-based platform is known for its accessible user interface, with easy and clear export options.

Function comparison of 5 software tools to support the systematic review process

Eppi-reviewer.

EPPI-Reviewer is a web-based software programme developed by the Evidence for Policy and Practice Information and Co-ordinating Centre  (EPPI) at the UCL Institute for Education, London .

It provides comprehensive functionalities for coding and screening. Users can create different levels of coding in a code set tool for clustering, screening, and administration of documents. EPPI-Reviewer allows direct search and import from PubMed. The import of search results from other databases is feasible in different formats. It stores, references, identifies and removes duplicates automatically. EPPI-Reviewer allows full-text screening, text mining, meta-analysis and the export of data into different types of reports.

There is no limit for concurrent use of the software and the number of articles being reviewed. Cochrane reviewers can access EPPI reviews using their Cochrane subscription details.

EPPI-Centre has other tools for facilitating the systematic review process, including coding guidelines and data management tools.

CADIMA is a free, online, open access review management tool, developed to facilitate research synthesis and structure documentation of the outcomes.

The Julius Institute and the Collaboration for Environmental Evidence established the software programme to support and guide users through the entire systematic review process, including protocol development, literature searching, study selection, critical appraisal, and documentation of the outcomes. The flexibility in choosing the steps also makes CADIMA suitable for conducting systematic mapping and rapid reviews.

CADIMA was initially developed for research questions in agriculture and environment but it is not limited to these, and as such, can be used for managing review processes in other disciplines. It enables users to export files and work offline.

The software allows for statistical analysis of the collated data using the R statistical software. Unlike EPPI-Reviewer, CADIMA does not have a built-in search engine to allow for searching in literature databases like PubMed.

DistillerSR

DistillerSR is an online software maintained by the Canadian company, Evidence Partners which specialises in literature review automation. DistillerSR provides a collaborative platform for every stage of literature review management. The framework is flexible and can accommodate literature reviews of different sizes. It is configurable to different data curation procedures, workflows and reporting standards. The platform integrates necessary features for screening, quality assessment, data extraction and reporting. The software uses Artificial Learning (AL)-enabled technologies in priority screening. It is to cut the screening process short by reranking the most relevant references nearer to the top. It can also use AL, as a second reviewer, in quality control checks of screened studies by human reviewers. DistillerSR is used to manage systematic reviews in various medical disciplines, surveillance, pharmacovigilance and public health reviews including food and nutrition topics. The software does not support statistical analyses. It provides configurable forms in standard formats for data extraction.

DistillerSR allows direct search and import of references from PubMed. It provides an add on feature called LitConnect which can be set to automatically import newly published references from data providers to keep reviews up to date during their progress.

The systematic review Toolbox is a web-based catalogue of various tools, including software packages which can assist with single or multiple tasks within the evidence synthesis process. Researchers can run a quick search or tailor a more sophisticated search by choosing their approach, budget, discipline, and preferred support features, to find the right tools for their research.

About this guide.

Our team has been developing literature review software for the world’s leading research organizations for over 15 years. Though the software has evolved dramatically over that period, the questions we are asked about the features and benefits of review software haven’t changed much.

In this guide, we present a comprehensive list of things to consider when evaluating a literature review software solution.

This guide will:

• Explain what literature review software does and how it is used
• Discuss where literature review software fits within the overall review process
• Provide a checklist of features to help you with the evaluation process

Who should read this guide?

If you are doing literature reviews today, you already know that they are increasingly required for regulatory compliance and safety monitoring. You also probably know that, while reviews sound simple on the surface, they are big projects that can consume significant amounts of time and resources. Doing reviews well can be a challenge.

This guide can benefit you if:

You are struggling with the amount of time it takes to conduct a review

If you are involved in the preparation of literature reviews for Clinical Evaluation Reports (CERs), Performance Evaluation Reports (PER), or if you track literature for safety monitoring, you need to be able to enforce standardized review processes and methods across your organization. Since your work could be subject to an audit, you need to be prepared.

You need to reduce the time it takes to conduct a review

You’re concerned about manual errors compromising the quality of your review

Did I make a transcription error? Did we forget to review that paper by Nosyk? Has any of my data changed? Worries like these can keep a researcher up at night and can seriously impact the quality and integrity of your review.

You’re not sure which literature review software is the best fit for you

What does literature review software do.

Today’s literature review software automates the many manual tasks involved in conducting a review. Literature reviews are process intensive and data heavy, and not so long ago they typically involved circulating paper copies of articles and screening forms to the review team who captured their work on spreadsheets.

Most reviewers currently use some form of technology to help manage the information and data in their review projects. In fact, a recent survey showed that the vast majority of reviewers still use spreadsheets at some stage of their review process.

Of course, it is possible to produce results using spreadsheets, or even paper forms. That said, each of these methods has a number of drawbacks that can have significant impact on both the quality and the volume of research produced.

Just Say No To Spreadsheets

When using spreadsheets for review tasks such as screening, data extraction, or storing references, you may find yourself dealing with some or all of the following:

• A reviewing “bottleneck” because each stage of the review must be completed before the next one is started
• Manual data entry errors that can be difficult or even impossible to catch
• Excessive manual work in checking for disagreements and creating reports
• Questions about the validity of your results due to lost files or undocumented processes

Where does literature review software fit in the process?

Literature review software is designed to reduce the manual work involved in conducting reviews and maintain a complete record of the work that’s been done on your review projects.

But how does it do this?

Once you’ve defined your research question and completed your search of relevant databases, you can typically import your search results into your literature review software and start your screening and data extraction processes.

Similar to the paper forms used in the past, literature review software uses electronic forms to record the answers to inclusion/exclusion questions. Some forms can be configured for data extraction. One of the main advantages that electronic forms provide is that they collect all your review data in one place, eliminating the need to manually cut and paste collate individual responses for processing and analysis. 

“Why input data twice when it only needs to be done once?”

Digital forms can be reused an unlimited number of times. Depending on the form and the reviewer, they can usually be completed faster than writing or typing since they can incorporate easy-to-use answer formats like checkboxes or radio buttons. They can also validate your data and even perform calculations before you submit it, giving you cleaner results and fewer errors.

Screening and data extraction are the most common review tasks facilitated by literature review software, but there are often other valuable features such as direct connection to popular databases such as PubMed, automated report generation, and reviewer roles and permissions management.

With regulatory bodies calling for continuous monitoring and assessment of safety data, having your entire review project and all its references, full text articles and audit trail stored within your literature review software can be a huge time saver when it comes time for updates.

As literature reviews have become a fundamental component of the risk management system for many organizations, they are increasingly scrutinized for thoroughness, standardized processes, and data integrity. By maintaining complete, accurate records of every reviewer action and decision, and allowing you to establish and enforce repeatable processes, literature review software makes it easier to deliver regulatory compliant, audit-ready literature reviews on time and on budget.

Top 5 Ways Systematic Review Software Can Help You

#1 compliance.

If there’s one thing that almost every reviewer wishes for, it’s more time. In our Survey of Literature Reviews, approximately one quarter of the respondents mentioned their greatest review challenge is the time involved in completing a review – to conduct searches, remove duplicates and irrelevant articles, complete screening, extract data, and prepare reports. In a recent survey of our user community, reviewers reported that literature review software reduced the time required to produce reviews by 40%-60%.

#3 Automation

No one wants to discover a mistake in their review right before – or worse, during – an audit.

Duplicate references, transcription errors, and data entry errors can skew, or even invalidate, your results. Literature review software can provide built-in automation and validation tools that dramatically reduce the potential for errors in your reviews.

#4 Compatibility

Although literature review software can help with many tasks throughout the review lifecycle, your process likely includes other tools for searching and storing references and data. You also likely need to use the information from your completed review in reports and submissions. Your literature review software should allow you to import and export your data in all the most common file formats, such as CSV, Excel, Word, PDF, RIS, and ENLX.

#5 Collaboration

Literature review software packages today are typically cloud-based and can be used from any browser on any device. With a centralized, shared data set, your team can collaborate in real time, regardless of location.

Your Literature Review Software Checklist

Deciding to adopt literature review software is more than just a monetary investment – it’s a commitment to a new way of doing things. And just like any significant purchase, it’s always a good idea to do your research first.

Make sure you conduct a thorough assessment of each of the available options to choose the software that is the best fit for your needs. Below is a list of features that may be offered by systematic review software packages.

7 open source tools to make literature reviews easy

Opensource.com

A good literature review is critical for academic research in any field, whether it is for a research article, a critical review for coursework, or a dissertation. In a recent article, I presented detailed steps for doing  a literature review using open source software .

The following is a brief summary of seven free and open source software tools described in that article that will make your next literature review much easier.

1. GNU Linux

Most literature reviews are accomplished by graduate students working in research labs in universities. For absurd reasons, graduate students often have the worst computers on campus. They are often old, slow, and clunky Windows machines that have been discarded and recycled from the undergraduate computer labs. Installing a flavor of GNU Linux will breathe new life into these outdated PCs. There are more than 100 distributions , all of which can be downloaded and installed for free on computers. Most popular Linux distributions come with a "try-before-you-buy" feature. For example, with Ubuntu you can make a bootable USB stick that allows you to test-run the Ubuntu desktop experience without interfering in any way with your PC configuration. If you like the experience, you can use the stick to install Ubuntu on your machine permanently.

Linux distributions generally come with a free web browser, and the most popular is Firefox . Two Firefox plugins that are particularly useful for literature reviews are Unpaywall and Zotero. Keep reading to learn why.

3. Unpaywall

Often one of the hardest parts of a literature review is gaining access to the papers you want to read for your review. The unintended consequence of copyright restrictions and paywalls is it has narrowed access to the peer-reviewed literature to the point that even Harvard University is challenged to pay for it. Fortunately, there are a lot of open access articles—about a third of the literature is free (and the percentage is growing). Unpaywall is a Firefox plugin that enables researchers to click a green tab on the side of the browser and skip the paywall on millions of peer-reviewed journal articles. This makes finding accessible copies of articles much faster that searching each database individually. Unpaywall is fast, free, and legal, as it accesses many of the open access sites that I covered in my paper on using open source in lit reviews .

Formatting references is the most tedious of academic tasks. Zotero can save you from ever doing it again. It operates as an Android app, desktop program, and a Firefox plugin (which I recommend). It is a free, easy-to-use tool to help you collect, organize, cite, and share research. It replaces the functionality of proprietary packages such as RefWorks, Endnote, and Papers for zero cost. Zotero can auto-add bibliographic information directly from websites. In addition, it can scrape bibliographic data from PDF files. Notes can be easily added on each reference. Finally, and most importantly, it can import and export the bibliography databases in all publishers' various formats. With this feature, you can export bibliographic information to paste into a document editor for a paper or thesis—or even to a wiki for dynamic collaborative literature reviews (see tool #7 for more on the value of wikis in lit reviews).

5. LibreOffice

Your thesis or academic article can be written conventionally with the free office suite LibreOffice , which operates similarly to Microsoft's Office products but respects your freedom. Zotero has a word processor plugin to integrate directly with LibreOffice. LibreOffice is more than adequate for the vast majority of academic paper writing.

If LibreOffice is not enough for your layout needs, you can take your paper writing one step further with LaTeX , a high-quality typesetting system specifically designed for producing technical and scientific documentation. LaTeX is particularly useful if your writing has a lot of equations in it. Also, Zotero libraries can be directly exported to BibTeX files for use with LaTeX.

7. MediaWiki

If you want to leverage the open source way to get help with your literature review, you can facilitate a dynamic collaborative literature review . A wiki is a website that allows anyone to add, delete, or revise content directly using a web browser. MediaWiki is free software that enables you to set up your own wikis.

Researchers can (in decreasing order of complexity): 1) set up their own research group wiki with MediaWiki, 2) utilize wikis already established at their universities (e.g., Aalto University ), or 3) use wikis dedicated to areas that they research. For example, several university research groups that focus on sustainability (including mine ) use Appropedia , which is set up for collaborative solutions on sustainability, appropriate technology, poverty reduction, and permaculture.

Using a wiki makes it easy for anyone in the group to keep track of the status of and update literature reviews (both current and older or from other researchers). It also enables multiple members of the group to easily collaborate on a literature review asynchronously. Most importantly, it enables people outside the research group to help make a literature review more complete, accurate, and up-to-date.

Wrapping up

Free and open source software can cover the entire lit review toolchain, meaning there's no need for anyone to use proprietary solutions. Do you use other libre tools for making literature reviews or other academic work easier? Please let us know your favorites in the comments.

10 Open Science Tools for Literature Review You Should Know about

Here are 10 literature search tools that will make your scientific literature search faster and more convenient. All of the presented literature review software is free and follows Open Science principles.

Traditionally, scientific literature has been tucked away behind paywalls of academic publishers. Not only is the access to papers often restricted, but subscriptions are required to use many scientific search engines. This practice discriminates against universities and institutions who cannot afford the licenses, e.g. in low-income countries. Closed publishing also makes it hard for persons not affiliated with research institutes, such as freelance journalists or the public, to learn about scientific discoveries. 

The proportion of research accessible publicly today at no cost varies between disciplines . While in the biomedical sciences and mathematics, the majority of research published between 2009 and 2015 was openly accessible, this held true only for around 15 percent of publications in chemistry. Luckily, the interest in open access publishing is steadily increasing and has gained momentum in the past decade or so.

Many governmental funding bodies around the world nowadays require science resulting from grant money they provided to be available publicly for free. The exact requirements vary and UNESCO is currently developing a framework that specifies standards for the whole area of Open Science. 

Once I started my research on the topic, I was astonished by just how many free Open Science tools for literature review already exist! Read on below for 10 literature search tools — from a search engines for research papers, over literature review software that helps you quickly find open access versions of papers, to tools that help you save the correct citation in one click.

Tools for Literature review

First, an overview of the literature search tools in this blog post:

ScienceOpen

• Citation Gecko
• Local Citation Network

ResearchRabbit

• Open Access Button
• EndNote Click

Read by QxMD

I divided the tools into four categories:

Search engines for research papers

• Literature review software based on citation networks
• Locating open access scientific papers, and
• Other tools that help in the literature review

Here, we go!

The best place to start a scientific literature search is with a search engine for research papers. Here are two you might not have heard of!

Want to perform a literature search and don’t want to pay for Web of Science or Scopus or perhaps you are tired of the limited functionality of the free Google Scholar ? ScienceOpen is many things, among others a search engine for research papers. Despite being owned by a private company, this scientific search engine is freely accessible with visually appealing and functional design. Search results are clearly labelled for type of publication, number of citations, altmetrics scores etc. and allow for filtering. You can also access citation metrics, i.e., display which publications have cited a certain paper.

Recommended by a reader of the blog (thank you!), the Lens is a search tool that doesn’t only allow you to search the scholarly literature but patents too! Millions of patents from over 95 jurisdictions can be searched. The Lens is run by the non-profit social enterprise Cambia. The search engine is free to use for the public, though charges occur for commercial use and to get additional functionality.

Literature Review software based on citation networks

The next category of tools we will be looking at are a bit more advanced than a simple search engine for research papers. These literature search tools help you discover scientific literature you may have missed by visualising citation networks.

Citation Gecko 

The literature search tool Citation Gecko is an open source web app that makes it easier to discover relevant scientific literature than your average keyword-based search engine for research papers. It works in the following way: First you upload about 5-6 “seed papers”. The program then extracts all references in and to these seed papers and creates a visual citation network. The nodes are displayed in different colours and sizes depending on whether the papers are citing a seed paper or are cited by it and how many, respectively. By combing through the citation network, you can discover new papers that may be relevant for your scientific literature search. You can also increase your citation network step by step by including more seed papers. 

This literature review tool was developed by Barney Walker , and the underlying citation data is provided by Crossref and Open Citations .

Local Citation Network 

Similar to Citation Gecko, Local Citation Network is an open source tool that works as a scientific search engine on steroids. Local Citation Network was developed by Physician Scientist Tim Wölfle. This literature review tool works best if you feed it with a larger library of seed papers than required for Citation Gecko. Therefore, Wölfle recommends using it at the end of your scientific literature search to identify papers you may have missed. 

As an alternative to the literature search tools Citation Gecko and Local Citation Network, a reader of the blog recommended ResearchRabbit . It’s free to use and looks like a versatile piece of literature review software helping you build your own citation network. ResearchRabbit lets you add labels to the entries in your citation network, download PDFs of papers and sign up for email alerts for new papers related to your research topic. Instead of a tool to use only once during your scientific literature search, ResearchRabbit seems to function more like a private scientific library storing (and connecting) all the papers in your field.

Run by (former) researchers and engineers, ResearchRabbit is partly financed through donations but their website does not state where the core funding of this literature review software originates from.

Locating open access scientific papers

You may face the problem in your scientific literature search that you don’t have access to every research paper you are interested in. I highly recommend installing at least one of the open access tools below so you can quickly locate freely accessible versions of the scientific literature if available anywhere.

Open Access Button 

Works like the scientific search engine Sci-hub but is legal: You enter the DOI, link or citation of a paper and the literature review tool Open Access Button displays it if freely accessible anywhere. To find an open access version, Open Access Button searches thousands of repositories, for example, preprint servers, authors’ personal pages, open access journals and other aggregators such as the COnnecting REpositories service based at The Open University in the UK ( CORE ), the EU-funded OpenAire infrastructure, and the US community initiative Share . 

If the article you are looking for isn’t freely available, Open Access Button asks the author to share it to a repository. You can enter your email address to be notified once it has become available. 

Open Access Button is also available as browser plugin, which means that a button appears next to an article whenever a free version is available. This search engine for research papers is funded by non-profit foundations and is open source. 

Unpaywall 

Unpaywall is a search engine for research papers similar to Open Access Button — but only available as browser plugin. If the article you are looking at is behind a paywall but freely accessible somewhere else, a green button appears on the right side of the article. I installed it recently and regret not having done it sooner, it works really smoothly! I think the plugin is a great help in your scientific literature search.

Unpaywall is run by the non-profit organisation Our Research who has created a fleet of open science tools.

EndNote Click 

Another browser extension that lets you access the scientific literature for free if available is EndNote Click (formerly Kopernio). EndNote Click claims to be faster than other search engines for research papers bypassing redirects and verification steps. I personally don’t find the Unpaywall or Open Access Button plugins inconvenient to use but I’d encourage you to try out all of these scientific search engines and see what works best for you. 

One advantage of EndNote Click that a reader of the blog told me about is the side bar that appears when opening a paper through the plugin. It lets you, for example, save citations quickly, avoiding time-consuming searches on publishers’ websites. 

As the reference manager, EndNote Click is part of the research analytics company Clarivate.  

Other tools for literature review

This last category of literature search tools features a tool that creates a personalised feed of scientific literature for you and another that makes citing the scientific literature effortless.

Available as an app or in a browser window, the literature review tool Read lets you create a personalised feed that is updated daily with new papers on research topics or from journals of your choice. If there is an openly accessible version of an article, you can read it with one click. If your institution has journal subscriptions, you can also link them to your Read profile. Read has been created by the company QxMD and is free to use. 

CiteAs 

You discovered a promising paper in your scientific literature search and want to cite it? CiteAs is a convenient literature review tool to obtain the correct citation for any publication, preprint, software or dataset in one click. Funded by the Alfred P. Sloan Foundation, CiteAs is operated partly by the non-profit Our Research . 

Beyond literature review tools

There you have it, 10 tools for literature review that are all completely free and follow Open Science principles.

Of course, finding a great literature review tool, such as a search engine for research papers or a citation tool, is only one essential part in the whole process of writing a scientific paper. If you would like to learn a complete process to write a scientific article step by step, then you’ll love our free training.
