i canāt pick a single fav website but. i wrote my thesis on queer history and loved looking thru these in the process
ACT UP Historical Archive - itās an archive of ACT UP NYās old website with a bunch of cool resources and things to read about the history of the movement to end the AIDS crisis. highly recommend exploring it
JD Doyle Archives - this guy created an amazing archive of both queer music history and Texas queer history and has digitized it online. imo it also really speaks to the role of ācommunity archivistsā in preserving the history of marginalized communities
Digital Transgender Archive - self explanatory maybe but itās a really cool archive of trans history across the world and thereās a map feature!!
