NLM Classification Fundamentals

Classification (Class) Numbers

Table G/Geographic Notation

Geographic Tables

Geographic subdivision is provided for certain numbers in the NLM Classification schedules by the application of Table G. Table G is a cutter system of notations that provides geographical or jurisdictional arrangement of materials under specific class numbers in the NLM Classification.

The use of Table G permits a shelving order which is controlled geographically and alphabetically (generally). Table G information is not supplied in the NLM Classification Index. You can view the Table G geographic Cutter tables here.

The geographic tables of the NLM Classification consist of nine geographic regions. Additionally, special provision is made for international agencies that frequently publish materials related to medicine.
