Errm... kind of...
A lot of books exist out there in plain html or .txt type, so if you have the original, or know a passage from it (preferably reasonably obscure, but word for word) just type it into google and see what comes up.
For an awful lot of classics, there's complete versions easily available.
So far I know of a collection of the complete works of H.P. Lovecraft and the Hitch Hikers Guide to the Galaxy (complete series), along with a few more that I haven't bothered to remember. I assume there's a lot more than just those...
