Books are a great source for historical information and images. Our library is organized based on subject matter, so chances are that if you find a helpful book on our shelf, there will be books on a similar topic organized next to and around it. You may find a great book by physically browsing the shelves in a way that you wouldn't necessarily see by using Summon or our online library catalog.
Ebooks are electronic versions of a book. In order to access them in our collections, you can either search in Summon and limit your results by clicking the "eBook Full Text Online" box; or from the UC Libraries Catalog under Material Type you can select Book and under Electronic Resource select Internet Resource.
