Probably not a 100% complete list, and of course will probably always be in flux. As it is, I had to dig through my librarything library to find some of the ones I knew I was forgetting. I’ve put stars in front of my absolute mostest ever favorites in the world — these are the books that I love so much that I often own more than one copy, just in case. A few of these are out-of-print, but are at least still accessible via libraries, bookmooch, and used book stores. As I get around to posting reviews of these books, I’ll link to the reviews from here.
