Discogs is an online database and marketplace for audio recordings, including commercial releases, promotional releases, and bootleg or off-label releases. Database contents are user-generated, and described in The New York Times as "Wikipedia-like", and users can purchase vinyl records, CDs, or cassette tapes from online sellers. While the site was originally created with the goal of becoming the largest online database of electronic music, it now includes releases in all genres and on all formats. By 2015, it had a new goal: that of "cataloging every single piece of physical music ever created." As of 2025, its database contains over 18 million user-submitted album listings.
