Saint Martin's University - O'Grady Library

Library of Congress Classification schedule

Books in the O'Grady Library--with the exception of those in Curriculum Resources--are classified and shelved according to the Library of Congress Classification System. An LC call number is assigned to a book based on its subject, so books examining the same topic should be shelved together. As an introduction to LC classification, this page provides a summary of the LC classification schedule. See Locating a Call Number for help finding LC call numbers on the shelves.
