Library of Congress Call Numbers

Piedmont Tech uses the Library of Congress Classification System to organize most of our physical resources.

Each item is labeled with a unique call number that indicates the item's proper place on the library shelves. Call numbers are primarily based on subject matter and can be helpful if you are trying to locate information on a certain topic. The information below matches Library of Congress call number groups with the subjects that they represent:
