Depending on your library, it may be any two of:
Library of Congress Classification
Dewey Decimal Classification
SuDocs Classification
NLM Classification
or others, even home-grown classification systems.
If your library is a federal depository library it almost certainly uses SuDocs for its collection of government documents.
If your library serves a medical school, it may use NLM (National Library of Medicine) classification for its medical collection.

Libraries classify books to allow for easy retrieval. A library can have hundreds upon hundreds of books (if not thousands or millions of books), and the only way for people to be able to find what they need, there has to be a system in place to organize the collection. Classification not only allows for specific titles to be located, but also allows for browsing of the stacks.
Non-Fiction books are classified by being divided into predetermined subject groups, according to the classification system being used by a library. The Dewey Decimal Classification (DDC) system consists of ten main subject groups (called categories), which ranges from 000 to 999 (e.g. 020.11). The Library of Congress Classification (LCC) system uses an alphanumeric scheme, which ranges from A to Z (e.g. PZ7.J684 Wj 1982).

The Dewey Decimal Classification system is a library classification system used to organize books by subject. It assigns unique numerical codes to different subjects to help libraries arrange books by topic, making it easier for users to locate specific materials.
There are two main classification systems for books in US libraries. One is known as the Dewey Decimal system and the other is called the Library of Congress system.
