Library of Congress classification schedule

Books in 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. This page offers a summary of the LC classification schedule. For more details, see the Library of Congress classification outline.

See locating a call number for help finding LC call numbers on the shelves.
