The problem with working on Scriblio is that I end up running into so many interesting looking books. Just this morning I discovered a number of recent acquisitions in the 19th Century and 20th Century subject feeds in my development instance (also available via RSS).
All of this is under active development, so those links may or may not work, and the site is definitely changing URLs soon. Still, I had to bookmark these books somehow so I could come back to them.
