The library classification system is the way that books, videos, and other items are put in order on the shelf. In other words, it is how we find the things we have in the library.
Classification systems use Call Numbers to mark where the book goes. Think of the call number like an address, it tells you where the book lives on the shelf.
Books and media are shelved according to the Library of Congress (LC) Classification System (shown above) in the libraries at Austin Community College. In addition to LC, on selected campuses only, health sciences books and media are classified and shelved according to the National Library of Medicine (NLM) Classification System.
