Questia is an online commercial digital library of books and articles with an academic orientation, with a particular emphasis on books and journal articles in the humanities and social sciences. The great majority of items are under copyright, for which Questia has paid a fee to the copyright owners. All the text in all the Questia books and articles is available to subscribers. The similar service Google Book Search has 7 million books scanned in their library, but users can only see small parts of copyrighted books. Questia offers some information for free, including several public domain works, publication information, tables of contents, the first page of every chapter, Boolean searches of the contents of the library, and short bibliographies of available books and articles on some 6500 topics.
