FAQ
What can you use Litmaps for?
You can use Litmaps to discover relevant academic papers, organize sources, and understand how studies connect through citations and references. If you are preparing a thesis, dissertation, or research article, its visual maps can help you explore influential publications, identify related studies, and build a clearer foundation for your literature review.
How does Litmaps help with literature reviews?
Litmaps supports literature reviews by finding related studies and displaying their citation relationships visually. You can start with a relevant paper, explore connected publications, and save useful sources for further reading. This approach helps you organize research more efficiently, although you must still evaluate each paper and synthesize the evidence yourself.
Is Litmaps free to use?
Yes, Litmaps offers a free plan for researchers who want to explore its core literature discovery features. Free accounts have limits on searches, maps, and articles, while paid plans provide expanded capabilities. Check the official pricing page before subscribing because plan limits, prices, and included features may change over time.
Can Litmaps help you find research papers?
Yes, Litmaps helps you discover academic papers through citation connections, references, and related research. You can begin with a known article or search for a topic, then explore suggested publications that may otherwise be difficult to find. Combining these results with database searches can improve the coverage of your research.
Is Litmaps useful for PhD students?
Litmaps can be especially useful for PhD students managing extensive reading lists and developing their research questions. Visual maps help reveal connections between foundational studies and newer publications. You can also monitor developments in your field. However, you should independently assess research quality and follow your university's literature review requirements.
Can Litmaps identify research gaps?
Litmaps can help you investigate potential research gaps by showing connections among existing studies and highlighting areas that may deserve further investigation. You might notice underexplored relationships or limited coverage of a topic. However, an apparent gap on a map is not proof that no relevant research exists, so conduct additional searches before drawing conclusions.
