For print books: click the link to see if your book is available in the library, then write down the call number to find your book in the library stacks.
For e-books: Click the link. Most links will take you directly to the book. If a link does not take you directly to the book, look on the page that opened for the "View it" section and click that link.
Reference books are available in the library. They do not check out, but sections can be copied and scanned in the library.
