ZSR Public Services Student Assistant Guide: Library of Congress Classification System

This guide is for students working in Public Services.

Explaination of LC

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.

Explanation of LCC Call Numbers

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.

NA2699
A446

is shelved before

NA2699
A46

EDITION NUMBERS

Dates are added to the call number to distinguish between different editions of the same book.

PQ394
P79
is shelved before

PQ394
P79
1976

PQ394
P79
C99
is shelved before

PQ394
P79
C99
1976

A copy number is used to distinguish between different copies of the same book.

PN3750
B96

PN3750
B96
c.2

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

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/Current Periodicals

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.
