Call Numbers in Mathematical Sciences: Home

Library of Congress Classification System

Books and journals are arranged on our shelves according to the Library of Congress (LC) classification system. Using this system, each book or journal is assigned an alphanumeric call number based on its subject focus. This call number uniquely identifies the item and places it on our shelves near other material on the same subject
