A suit brought by five book publishers against Google for copyright infringement could spell the end regarding how information searches on the Internet are carried out. The publishers claim that Google is exceeding the free use of limited portions provision of the law by making digital copies of entire books. Professor Jessica Litman, who teaches Internet law at Wayne State University , points out that Google intends to use only limited extracts from books for an index, and indexes traditionally have been deemed fair use under the law.
