ZSR Library, along with most other academic libraries, uses the Library of Congress Classification system to organize our collection. You will be learning about this system and how to shelve books in the correct location according to this system prior to working in Stacks.
Call numbers are composed of both letters and numbers, but all call numbers will start with a letter (or letters). Please browse below for an overview of the general subject indicated by the initial letters of a call numbers, and where these sections can be found within our library.

CLASSIFICATION NUMBERS
Book and Journals are cataloged according to their subject matter. The first letter of the call number indicates the subject.
N- Fine Arts
D- History
A second letter may follow which represents a subdivision of the subject.
NA- Architecture
DC- French History
A counting number which further subdivides the class follows the letter.
NA2699- Architectural Design and Drawing
DU80- Australia
AUTHOR NUMBERS
Author numbers distinguish between books with the same classification number. The author number consists of a letter and a decimal number.
NA2699
A53
DU80
A142
When the first line of the call number and the letter of the author are identical, the books are put in order by the decimal number following the author letter.

D AND K CALL NUMBER ORDERS
Some books with D or K call numbers will sometime have three call letters rather than the traditional one or two. For Example:
KFN17
A22
C34
Therefore, KFN would be shelved before KFP, KFR, KFV, etc.
The same can be said about D call numbers similar to this format. For Example:
DJK28
A17
D45
Therefore, DJK would be shelved AFTER DJ and BEFORE DP, DR, etc.
Government Documents are shelved on Reynolds 4 in the Government Documents Department. The Government Document call number is very different from the Library of Congress call number used on other books. The Government Document call number uses a system of colons, dashes, and spaces. The call numbers can look like this: NAS1.21: 474/v.2/Bk. 1 Government Documents include books, bound volumes, maps, pamphlets, and leaflets.
Reference Department books and Current Periodicals are shelved on Wilson 4. The Reference Department books are separate from the Main Stacks. Their call numbers are the same as books in the Main stacks, but indicated with an REF above the call numbers. Example: REF PN1993.5 A6 B55 2007.
Current Periodicals are in alphabetical order by title on the shelves on Wilson 4.
