Online books - update

A while back, I wrote about Google Books and Live Search Books. Microsoft announced last week that they are ending the Live Search Books Project (apparently the existing books they have scanned will still be available via the main Live Search - but no word on whether this will be restricted to US visitors or not, as the Books feature had been). Sad news for those of us who love books and love coming across hidden gems online - has anyone found anything interesting books online lately?
