How are book previews limited? [from books.google.com]:
·  Many of the books you can preview on Google Books are still in copyright, and are displayed with the permission of publishers and authors. You can browse these "limited preview" titles just as you would in a bookstore, but you won't be able to see more pages than the copyright holder has made available.
·  When you've accessed the maximum number of pages allowed for a book, any remaining pages will be omitted from your preview. You can order full copies of any book using the "Get this book" links to the side of the preview page.
