In case you haven't seen it yet, the Open Library is now the National Emergency Library, which means you can borrow ebooks with no waitlist. They've got over a million books--I did a broad search last night for science fiction and fantasy, and they've got a ton of books, both well-known and obscure, from the mid-1990s and further back; adult, YA, middle grade, and kids. Especially when I got to the 1970s and 80s, it was like scanning the shelves at my childhood library and bookstore trips.*

Formats tend to be epub, PDF, and encrypted daisy for print-disabled users. [rachelmanija points out this online ebook conversion service for other formats. Don't know if there's DRM on the books that will stop it or not.]

Robotech books! Star Trek novels! A bunch of other good and terrible books! If there's something that's out of print that you've been trying to get your hands on for a while, it's worth searching for it here. yhlee I saw The Visual Guide to Amber by Zelazny and someone else. I was reminded of tons of books I'd forgotten about. There's even this odd book I read years ago that was written by someone who was a Cepheid* before I was, and who set it in a thinly-disguised future version of College Station/Texas A&M, IIRC.


*Cepheids = members of Cepheid Variable, the science fiction club at A&M that ran Aggiecon for years.
