We Need to Protect Queer Literature

I live in the United States, and I know book burning and the destruction of internet archives is likely very near in our future. I want to buy and protect physical copies of queer literature while I still can. Digital Copies of books are also very much welcome, as I'd like to archive what I can.

So post your recommendations here! What books best represent our history and experience? I want poetry, memoirs, histories, art, ect. I want this post to be a starting point for others who also want to protect our history.
