LC Classification at Illinois

The University of Illinois Library has historically used Dewey Decimal classification for the majority of the library's collection, and it currently works in both Dewey and LC (see the list of Collections by Classification).

This guide presents an overview of using LC Classification at Illinois and any local policy decisions made regarding implementation of LC Classification.

LCC Procedure

When classifying a book in LC:

Use any suggested number from 050, verifying against the LC schedules
- If there is more than one suggested LC number, prefer the number in 050 00.
- If no 050 00, ask an LC resource person.
If there is no suggested number, construct one using the first subject heading in the record.
Check call number in Voyager for uniqueness using the Browse feature.

LC Cutters

When creating Cutter numbers for LC Classification, use the table from the Cataloging and Shelflisting Manual: G63 (below).

You can also use the Cataloging Calculator to determine Cutter numbers. Simply enter the first words of the main entry in the search box and select the LC Cutter option.
