You can also use UC Library Search to search for books across the UC system and around the world:
If you need a book or journal article that the UCLA Library does not own or is lost or missing, you can make an Interlibrary Loan (ILL) request and we will try to get it for you. Use the form linked on this page. There is no cost for making an ILL request, but you should allow one or two weeks for the item to arrive. Journal articles will most often be sent to you as a link to a pdf scan in your email.
