Potions and Sniches.net
Harry Potter fanfiction archive. It used to be PotionsAndSnitches.net. I started this site a long time ago under the name animealam, but was unable to manage it due to real life, so Jan-AQ took over becoming webmistress. I still kept paying for domain and server space until real life made it impossible for me to continue. I gave rights to the site to the current admims.
Multi fandom fanfiction archive (They have quite a selection of InuYasha fanfiction here.
Archive of Our Own
Fanfiction Archive for multiple fandoms. They have taken the fics from several Harry Potter fanfiction archives that were no longer able to continue paying server fees to keep on going.
Multi-fandom Fanfiction Archive They are probably one of the fanfiction archives with the largest collection Harry Potter fanfiction, but they also have a good number of fanfiction for multiple other fandoms, as well as crossovers.
