Mason Libraries uses the Library of Congress Classification system to arrange books on the shelves so that books on the same topic are shelved together. Each book has a unique call number that begins with one, two, or three capital letters followed by numbers. Most call numbers appear on the spine of the book or video. A call number is like an address - it tells where the book is located in the library.
