WNCLN Library Catalog
The catalog provides access to the combined library holdings of Appalachian State University, UNC-Asheville, and Western Carolina University.

Google Books is an excellent tool for perusing the contents of millions of books. 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.
