To find books and government documents in USA Libraries' collections, use SOUTHcat: USA Libraries' Catalog.
Google has agreements with some libraries to scan their collections. Google Books allows you to search the full text of these scanned books, but if the book is under copyright you will not be able to see the full text. If you find something interesting via Google Books, search the library catalog to see if it is available to you via the Marx Library or your public library.
