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.

BuzzData was a website that allowed users to create accounts to share and follow datasets. Data was shared in public rooms under open licenses. The service included tools to help visualize and present data.

BuzzData was closed on August 1, 2013.
