Library of Congress is a classification system most commonly used by research and academic libraries (much like Dewey for public libraries).
What is a call number?
In Library of Congress classification, subjects are arranged by letter (P is Language and Literature), then by subcategory (PS is American Literature). For a complete listing of subjects, visit the Library of Congress Classification Outline.
How do I find my library item?
It can be helpful to think of a call number as the address for the material. Each item has only one call number associated with it. It is also helpful to know which floor your item will be located on. So before hunting the stacks, take a look at our library maps or look at this list of the UI Library floor locations for selected LC classification letters.
