Fatcat (https://fatcat.wiki) is a publicly-editable bibliographic catalog, containing metadata about tens of millions of research articles, conference proceedings, and books. The particular emphasis is on linking different "releases" of the same "work" (eg, preprint and final copies of a journal paper), and matching specific (archived) files to releases.
Currently, Wikimedia/Wikipedia account linking is only used for signup and login. In other words, Fatcat gains no access to your personal account information and can make no mediawiki edits or other actions on your behalf.
Fatcat is a project of the Internet Archive (https://archive.org).
