Google Book Search is a controversial tool from Google that searches the
full text of books that Google scans and stores in its digital database.
The publishing industry and writers' groups have criticized the project's
inclusion of snippets of copyrighted works as infringement. The Authors Guild of
America and Association of American Publishers have separately sued Google,
citing "massive copyright infringement." Google claims its project represents a
fair use, and is the digital age equivalent of a card catalog with every word in
the publication indexed.
