What is a call number?


A call number is a unique code given to each item in the library. It identifies the subject and location of each book, journal, video, map, etc.

McPherson Library arranges most items using the Library of Congress (LC) Classification system, which uses call numbers that start with letters and also include numbers. You can use LC Classification to see which call numbers are used for your topic.

Material shelved in the  Curriculum collection  uses the Dewey Decimal System to classify items. Dewey call numbers start with numbers and often include letters.
