The Library of Congress Classification is the system used to organize books in Campbell Library. It is used by most but not all colleges and universities in the United States and Canada, as well as a few other countries. The other popular system in America, generally used in school and public libraries is of course the Dewey Decimal system. These are only two of many classification systems in used around the world.
The LC Classification system always begins with a letter. Subjects can be one, two, or sometimes three letters. These are followed by numbers which more specifically identify a topic. Using this system ensures that all like books are kept together on the library shelves.
Class B includes Philosophy, Psychology, and Religions. As you can imagine this is generally a big section in most academic libraries. Following is a breakdown of the LC Class subsets.
