Discogs, the crowdsourced online music marketplace popular among vinyl collectors, today announced it has surpassed another major milestone: the site now has over 9 million releases. The company said it has been averaging over 113,000 monthly submissions this year, with 120,000 logged last month thanks in part to its annual September Pledge Initiative (S.P.IN).

Since reaching the 8.5 million mark in June, Discogs has added an additional 20,000 contributors to the site, bringing that total to 375,000. When the milestone was 8 million releases, reached in early January, that number was 326,000 contributors, who feed the site's massive database with hyper-detailed album and single information, such as variations between label pressings, formats, vinyl color, liner note typos and production notes.

"What we're experiencing in the growth of contributors and submissions to the Discogs Database only echoes the thriving passion for music's physical formats," stated Chad Dahlstrom, COO of Discogs. "The Discogs Database mission will never lose focus on preserving physical releases in any format imaginable from every part of the World."

Discogs was founded in 2000 by then-Intel programmer Kevin Lewandowski, who started it as a hobby to catalog his collection of electronic albums. The site evolved into a user-generated database resembling a wiki, and tried a paid membership model before 2007, when it added a consumer-to-consumer marketplace feature where fans could buy and sell vinyl.

The marketplace now contains roughly 36 million items available to purchase. Unsurprisingly, the most popular format found in the database is vinyl (26.5 million), followed by CDs (8.6 million), cassettes (523,000), CDr (226,000) and DVDs (212,000).The most popular genres in the marketplace are electronic, rock, pop, funk/soul and jazz.

In addition to its flagship site, Discogs said it has experienced exponential growth across its family of recently launched sister sites, Bookogs, Filmogs, Comicogs, Gearogs, and Posterogs. According to the company, the September S.P.IN campaign helped those verticals surpass submission goals by nearly 600 percent. The network also has a handy site called VinylHub, which is like Discogs but cataloging record shops and keeping track of events near and dear to crate diggers everywhere.
