We're excited to announce that we've crossed another milestone: AO3 now has more than 18 million fanworks! A big Thank You to everyone who contributed to that success, whether you're a fanwork creator yourself, or cheering on your favorite creators with kudos and comments.

Of those 18 million fanworks, a lot live in collections. A collection is a group of works and/or bookmarks compiled together under one theme. You can, for example, group together works for a specific trope or relationship. Prompt Meme and Gift Exchange challenges for specific events are also hosted within collections!

Did you know we recently rolled out some changes adding new features to collections (fairly) recently? Our Accessibility, Design, & Technology committee published a post on it last September, if you want to check it out!

Some of the most important updates were:

  • giving collection owners the ability to add up to 10 tags to the collection that show up in the collection blurb
  • a "Multifandom" filter for collections containing works from more than one fandom
  • the automatic addition of fandom tags to collections as the feature went live (or the "Multifandom" tag for collections with works/bookmarks from many fandoms)

Some additional changes that were rolled out with the tag-feature as well: for example, the Open Challenges page (including the Open Gift Exchange and Open Prompt Memes pages) now shows collections that are closing soonest at the top of the page!

To try out the new features for yourself, you can head on over to the Collections page by selecting "Browse → Collections". Once there you can filter collections either by a specific tag, or include or exclude collections with the "Multifandom" tag. By selecting "Open Challenges" on the top right, you can browse currently open challenges. And if you want to learn more about how to navigate, create, or administrate collections, check out our Collections FAQ!

Thanks again for your continued support, time, and passion for fandom! We hope to celebrate many more milestones with you in the future.
