Books (as well as journals) are arranged on the shelf by call numbers. The call number is a unique identifier and is created using the Library of Congress Classification System. The rationale behind this alphanumeric system is to classify books by subject both broadly and specifically.
When looking for a book in our catalog, note that there are several different locations across the University system in which that book can be found. UNR has 3 main libraries: the Knowledge Center, DeLaMare and Savitt Medical. These are the most common locations for books in our catalog. The Knowledge Center also has an in-house storage system called MARS. When looking at the catalog, you can tell where a book is located based on the location column.
The easiest way to find a book is to look it up in the catalog. The book's catalog record tells you which library it's in, and when you click on the link "Floor Plan," it takes you to a library map showing you where the book is located.
After you determine the location in the library, you can find the book by locating the specific call number on the shelf. Here is a very helpful explanation of how to read call numbers so you can find a book on a shelf: http://guides.library.unr.edu/libservices?p=295414
If the book you want has the location of MARS, you can request it through our catalog by selecting the "Request from MARS" link. MARS requests usually take 10-15 minutes to be ready and can be picked up at the Library Services Desk at the Knowledge Center.
