Citeline was a tool for publishing bibliographies and citation collections on the web. It takes a BibTex file exported from Endnotes, Refworks and similar tools and turns the collection into an interactive, shareable exhibit. Citeline citation collections may also be exported in a variety of formats, such as BibTex, JSON, XML or tab-separated values.

The Citeline project has been retired, and the website is no longer available. Information about Citeline is currently only available via the Internet Archive.
