Google Book Search Book Search works just like a web search. Books that match your search terms will appear in your search results. If the book is out of copyright, or the publisher has given permission, you'll be able to see a preview of the book, and in some cases the entire text. If it's in the public domain, you're free to download a PDF copy.
