ScholarWorks can be used to publish a whole book online. It can be put up as one large PDF file or broken down into chapters. A "book gallery" is a hybrid between an image gallery and a normal series or Web page for scholary work. Each uploaded "book" will be displayed with an image of its cover and an abstract. When you click on the book, you will get more detailed information and can download the whole book or parts of the book.
Other universities have been using this feature to list new books published by faculty and linking out to Amazon or other booksellers. See Georgia State University in the left colum for an example.
