The LC Classification System is similar to Dewey, as it is also subject based, classifying and arranging items by the subject matter involved. Each piece of a LC call number is a classification that begins broad, getting more specific to the subject of the book with each number. Decimals also help the number get more specific.
However, the LC call numbers begin with letters, followed by various letters and/or number combinations. Each letter stands for a general subject area. By breaking items into 21 subject areas rather than the 10 of Dewey, the LC classification system allows libraries to classify and arrange larger collections.
LSU Libraries uses LC call numbers for most of it's books.
