Reading a Call Number

The Contra Costa College Library uses the Library of Congress system of call numbers (as opposed to the Dewey Decimal system used by most public libraries) to organize books and other materials on the shelves. The entire call number is a set of letters and numbers in several sections.

Searching for Call Numbers on the Shelves

Notice that each section of the call number starts over and items are filed in alphabetical or numerical order.
