The “Call No.” is the location on the library shelves where you will find a book, DVD, etc. The Las Vegas – Clark County Library District uses what is called the Library of Congress (LC) Classification system. This system uses letters and numbers to generate a unique “call number” or location the item can be found on the shelf.
The University of Pittsburg has put together a handy tutorial to explain how to read and find items classified with LC. After explaining the structure of call numbers you will be asked to order 8 books on the book shelf. After each successful completion you can try it again with another set of books. Test your skills with the LC Classification Tutorial.
