About Connected Papers
Connected Papers is a visual tool for exploring academic literature and understanding the relationships between papers. Start with one paper, and see a graph of connected works, helping you discover relevant research and understand the scholarly conversation.
Key Features
- ✓Visual Graphs: See papers as nodes in a graph, connected by citation relationships. Similar papers cluster together, making it easy to understand research areas.
- ✓Prior Works: Identify foundational papers that established the research area. These appear as larger nodes with many connections.
- ✓Derivative Works: Discover papers that build on or extend the original work. See how research has evolved from foundational ideas.
- ✓Co-Citations: Find papers that are frequently cited together, indicating they address similar questions or methodologies.
- ✓Bibliographic Coupling: See papers that cite the same references, suggesting they're working in related areas.
- ✓Interactive Exploration: Click any node to expand the graph around that paper, drilling down into specific research threads.
- ✓Search & Filter: Search within the graph by title, author, or year. Filter by connection type or publication date.
- ✓Export & Share: Export graphs as images or data. Share graphs with collaborators via URL.

Frequently Asked Questions
How does Connected Papers build the graph?
Connected Papers analyzes citation networks. Starting from a seed paper, it finds papers that cite it, papers it cites, and papers that share co-citations. These connections form the graph. Papers with many similar citation patterns cluster together visually, representing related research areas.
What do the node sizes and colors mean?
Larger nodes typically represent papers with more citations or more central positions in the network. Colors group papers by similarity — papers in the same color cluster tend to be closely related in terms of citations and research topic.
Can I use Connected Papers for any field of research?
Yes, Connected Papers works across all academic disciplines that have citation data. It's particularly useful in fields with well-established citation practices like sciences, social sciences, and humanities. Fields with limited citation data may show smaller graphs.
Is the academic discount available to students?
Yes, the Academic plan ($3/mo) is available to anyone with a valid .edu email address, including students, faculty, and researchers at academic institutions. You'll need to verify your email to qualify for the discounted rate.
