Library of Congress

What is the Library of Congress Classification System?

The Library of Congress system is used by most college and university libraries to organize books on the library shelves. It is an alpha-numeric system. Each item in the library has a label with letters and numbers (together called a call number) which indicates its place on the shelf. The letters indicate a subject area, and the numbers which follow further subdivide the broader topic into more specific categories. 

Start with a search in the library catalog or use the search box at the bottom of this page, and in your search results, you should notice the call numbers associated with physical items located within our libraries.
