There are a variety of ways to request items that the University Libraries do not currently own, or that are currently unavailable. Visit this page to see them (http://guides.library.unlv.edu/interlibraryloan/) . Often you will receive a pdf copy sent to your UNLV email account. This service is free to UNLV faculty, staff, and students! You may need to register your Rebel Card barcode with the libraries first.
Search this database listing books in libraries worldwide to discover what's been published on a subject. The Get Text button will link you to a Document Delivery Services form to request books from other libraries.
