Most academic libraries including the Millsaps-Wilson Library use the Library of Congress (LC) Classification System to arrange books and other items on the the library shelves. This system allows each item to be assigned a unique call number. A call number is like an address; it indicates where the item is located on the library shelves.
Most call numbers have four parts :
• General / Broad Subject
• Narrower subtopic
• Cutter Number (represents author, corporation, or title)
• Year of Publication
Some call numbers will also list volume or copy number as well.
