Library of Congress Classification


The Library of Congress classification system organizes books and other library materials according to subject, making it easy for you to browse the shelves for materials about a specific topic. Library of Congress call numbers begin with letters of the English alphabet. The letters identify the subject of the work, for example, the letter P at the beginning of a call number indicates that the work is about language or literature. The call number also functions as a location code. You will find it taped to the lower spine of each item. It also appears in the library's online catalog (CONSULS) in the full catalog record representing the physical item.

Example: P 1344 .S48 1987

The title of the work with this call number is Mark Twain's Languages: Discourse, Dialogue and Linguistic Variety

In the following outline of Library of Congress classification, the major subject divisions are indicated by a single letter. The major divisions are subdivided into more specific categories, indicated by double letters. For example, works about English literature are assigned call numbers that begin with the letters PR.

Example: PR 4552 .A 1948

The title of the work with this call number is David Copperfield, a work by the English novelist Charles Dickens.
