Litmaps

Great features of Litmaps

1. Interactive literature maps: Litmaps allows users to create interactive literature maps that show the relationships between articles in their collection in the form of connecting lines which trace the citations for them.

2. Discovery tools: Litmaps provides users with basic and advanced discovery tools that allow them to explore the space around their literature maps and refine their search results by author, date, and keyword..

3. User-friendly interface: Litmaps has a user-friendly interface that allows users to easily pull articles around, create groupings or subsets of articles in different colors, and tell whatever story makes sense to them.

Limitations of Litmaps include:

1. Limited number of input articles: The free version of Litmaps limits the number of input articles to 20, while the paid version, Litmaps Pro, provides unrestricted search access.

2. Litmaps uses Crossref as its only index of papers, which can be a limitation as it may not include all relevant articles4. This can lead to gaps in research and incomplete literature reviews.

3. Although Litmaps can help discover papers and fill gaps in research, it should not be used alone to complete a systematic review.
