Some Wikipedia:Books I've created on topics that interest me.

User:Diamond Blizzard/Books/On the Possibilities for Alien Life (actually, there seem to be two much more comprehensive Wikipedia books on astrobiology that I only noticed after I finished creating my own, and I'm not sure whether to delete this one or not)

User:Diamond Blizzard/Books/Hyperbolic Geometry: Concepts and History (this is probably better, as there doesn't seem to be any other Wikipedia book on hyperbolic geometry specifically)
