Area 52
For those of you who were into Stargate slash fanfic, you're probably familiar with the fic archive Area 52. It went offline in 2017 and no one has been able to contact the site owner about moving the archive to AO3.
So someone did the next best thing and created a bookmark list, which shows nearly 12K items. The links are external and will take you to the Internet Archive (aka Wayback Machine) capture of the page, though I did spot a couple that linked to a copy on AO3. You can still filter by rating, pairing, etc.
Nearly 12K fics. From what I recall of when fans started working on this, they managed to find all but a handful of fics from the site. You can read about the project in their profile.
