Library One Search is the best starting point for your research. It is like a Google search for resources in the ASU Library. You will retrive books, journal and magazine articles, dissertations, media and anything else that may be relevant from the Libraries' collections. A majority of items you retrieve include links to the full text online.
The first two Academic Search Premier and Humanities Full Text are the most useful for starting research.
A Google Books search can be invaluable for finding relevant information buried in books. Since Google Books can search through the whole text of a book title, you can uncover material that previously would have required you to read the whole book.
