Locations and Call Numbers

To find a book in the library, you need to know the location and the call number. Together, the location and the call number are like an address for the book -- they tell you exactly where the book can be found. To find the address of a particular book, such as The Adventures of Tom Sawyer, start with the UHD Library Catalog. The library catalog will give you the exact location and call number. To find a section of the library where you can browse all books of a particular type, such as business books, children's books, or geology books, a basic familiarity with library locations and call numbers can help you find the right place to start. Our library staff can also point you in the right direction. If you have any questions about how to find a book, please Ask a Librarian.

Understanding Locations

This is what a location looks like in the library catalog: DOWNTOWN/GENERAL COLL. The first part tells you the name of the library. The second part tells you the name of a collection in that library. Consult these charts for library and collection codes:

Understanding Call Numbers

Most call numbers are based on the Library of Congress Classification System, a method of arranging books that is commonly used by college and university libraries. These call numbers use letters and numbers to represent the subject of each book.

In the library catalog, Library of Congress call numbers look like this:

HF5415 .M374 2007

When you find a book on the shelf, the call numbers look like this:

HF
5415
.M374
2007

This chart explains how to read a Library of Congress call number:

HF

The first line represents a subject, such as business or geology. Read it in alphabetical order
i.e., A, B, C, D...H, HA, HB...HE, HF

5415

The second line represents a more specific subject. Read it as a whole number,
i.e., 1, 2, 3...50...100...1000...5000...5414, 5415

.M374

The third line usually represents the author.

Read the letter alphabetically. Then read the number as a decimal,
i.e., M36, M361, M362...M37, M371, M372, M373, M374

2007

The last line represents the year of publication. Read this number in chronological order.
