5,000 books available for free
Questia, a subscription (for profit) online full text supplier, has made over 5,000 public domain books available for free.
Access is only by title and author lists; no subject access. Still what do I want for nothing, my money back?
While I don’t enjoy browsing an electronic list as much as I like checking physical volumes on a shelf, a quick scan of this virtual collection included these titles for further exploration:
