BookBrainz is an open, community-driven project building an online database of books, magazines, journals, and other publications. Its goal is to document every publication ever written and make the collected data freely available for people around the world to use. The database includes information about authors, works, editions, and related entities, with records maintained and expanded through community contributions.

Anyone can take part, whether by editing existing information, contributing to the project’s development, or helping raise awareness. Visitors can browse recent database revisions and explore the project’s collections, statistics, and documentation. Those who want to contribute can learn more about the initiative and create a free account.

BookBrainz is part of the MetaBrainz community and invites users to help test its under-development software. It also welcomes feedback about bugs, glitches, and possible improvements through MetaBrainz JIRA. Community members can connect through Matrix, IRC, Discord, forums, Mastodon, Bluesky, or email. As an open database, BookBrainz aims to support shared knowledge about publications and make its information accessible for reuse.
