Online book-tracking service that allows people to enter a “collective library” on the Internet.

“Bibliophil allows its users to keep track of their books in a customized library with public/private library security available. Users can create Buddies with trust relationships, recommend books to buddies, and keep track of recommendations. Query their library and sort by title, author, rating, date read, etc. filter by author, unrated books, unread, reviewed on loan, wish lists, and for sale. Users can also export available via Excel (CSV) and have PDA and Mobile access to their libraries.” (From Bibliophil.org.)
