Citation Gecko is a free web tool developed by a team of researchers at the University of Lausanne, designed to help academics discover new literature through citation 'snowballing.' Its core feature is the ability to generate a network graph of papers by starting with an initial set of relevant articles and then exploring their shared citations and references. It's primarily built for academics, graduate students, and anyone undertaking a systematic literature review who needs to efficiently expand their knowledge base beyond keyword searches. Users typically open Citation Gecko when they have a few key papers and want to quickly identify both the foundational works they cite and the newer works that cite them. It operates entirely within a web browser and allows for easy export of discovered references in formats like BibTeX.
Why It’s Useful
Unlike traditional keyword searches, Citation Gecko leverages the power of citation networks, making it a highly effective method for discovering relevant papers that might otherwise be missed, complementing search engines like Scopus or Web of Science. For the master's student in the early stages of their thesis, it can rapidly build a comprehensive bibliography by identifying both backward and forward citations from their initial seed papers, ensuring no crucial work is missed. For the experienced researcher mapping a new sub-field, it helps identify influential papers and emerging research fronts by visualizing interconnectedness and key authors. It is completely free to use, supported by academic institutions, making it an accessible resource for researchers worldwide. A feature that users often discover later is the interactive graph, which allows filtering by year or number of citations, helping to pinpoint the most impactful papers in a dense network. Its niche focus on citation snowballing and its academic origins mean it's not as widely known as commercial database tools, despite its unique effectiveness. It is regularly updated by the developers and has growing academic use, fostering a collaborative research environment.
