Find the papers you didn’t know you needed and research with confidence

To get started, simply enter a DOI, Pubmed ID or arXiv ID, a keyword or an author’s name into the search box and Litmaps will generate a set of recommended articles for you. Pick an article (or a number of articles) from the list to create a Litmap, which uses your chosen article as the ‘seed’.

You can import a collection from Reference Managers to kick start your Discovery. Litmaps supports BibTeX and RIS files. You can even start your search from a pre-existing Litmap.

Litmaps Free limits your number of input articles to 20, whereas Litmaps Pro gives you unrestricted search access.


Once you’ve got a basic Litmap you’re going to want to explore the space around it to find related articles. To do this simply add more articles to your search, which will refine the recommendations Litmaps gives you.

Litmaps Free gives you access to our basic Discovery tools, whereas Litmaps Pro gives you the ability to search with a higher level of fidelity, allowing you to filter your search results by author, date and keyword.
Advanced Discovery Tools

Litmaps Pro gives you access to advanced Discovery tools. These tools allow you to dive deeper and do more nuanced searches.

  • Unlimited search inputs (within reason!)
  • Filter search results by date range, author and keyword
  • Access second-order citations from the Discovery graph


A Litmap shows the relationships between the articles in your collection in the form of connecting lines which trace the citations for you. You can visualize multiple collections simultaneously to bring your literature review to life.

By default, the most recent articles appear on the right hand side of the graph and the most cited articles appear at the top, so recent popular articles appear in top right hand corner.

Use your mouse to pull the articles around to tell whatever story makes sense to you. You can create groupings or subsets of articles in different colours to help tell your research story.

On Litmaps Free, you can have up to 100 saved articles on a single map. On Litmaps Pro there’s no limit to the number of articles or the number of maps.


A Litmap is a great way to communicate and share your work with those in your field.

You can easily share your Litmaps to Twitter, Linkedin, Facebook etc. using the share button next to your Litmap. You can also export it as an interactive link for inclusion in your blog, and of course, export it as an image for inclusion in your research.

If you’re using a Reference Manager, you can export your Litmap as a BibTex file and import it into your Research Manager which helps keep all your research in one place.


With Litmaps Pro you can ask Litmaps to monitor your saved searches and send you alerts when new articles are published that relate to your search. Monitoring helps you stay ahead of the research curve and focus more of your time on your work.
