How to read a Library of Congress Call Number (2022)

At the Porter Henderson Library, books are shelved according to the Library of Congress (LC) Classification system. Each book in the library has a unique “call number”, which is a combination of letters and numbers. A call number is like an address; it describes the exact location of the book and tells you where to find the book on the shelves. It also tells you something about the subject matter of the book. Each call number may contain three, four or five lines.
