I am 70% of the way through this year's storygraph reads the world and it's definitely exposed me to a lot of stuff I probably would've kept not reading otherwise lol I still have Lebanon, Jamaica and Sudan left (maybe I can cheat by finally reading my Jamaican friend's graphic novel...)
My interwar lesbian reading list includes Natalie Clifford Barney although I'm more interested in a biography of her than her novel TBH her Wikipedia page alone is WILD, Djuna Barnes's Ladies Almanack, Janet Foster though I don't think she wrote about lesbians necessarily she just was a lesbian writer then, Claudine at School by Colette, all of Marina Tsvetaeva's gay poems and letters but only her gay poems and letters, whatever Sophie Parnok did idk much about her, and I don't know how easily I'll get ahold of any of these titles because I think a lot of them are out of print in English lol but I've found Tsvetaeva's letter to Barney and I'm going to read it when I'm in the right headspace for it
If you like early female sff writers! James Tiptree is the only other name I know lol
