If we don't have access to a book or article you can borrow a copy from another library. Just search for the book in Williams WorldCat, and then choose "Request Item" to borrow it.
If you need help, just ask!
Many of our databases have this button, which searches for the full-text of the article in our collections. If we don't have it electronically, look for the "Request article scan" link in the "Get It" section.
