Expanded Country Notations

• While not practiced at NLM (with the exception of W2 serials), local institutions may expand Table G to better accommodate materials in their collection

• Table G provides a state or political unit breakdown only for the United States and Great Britain

• A work that is limited to a city, or a state, province or its equivalent, takes the geographic notation for the state or country, or for the smallest area below the national level that has its own notation

• Other heavily used state or country notations may be modified to form county (province, state, etc.) or city notations by the addition of .1 (county) or .2 (city) to the appropriate notation

• The modified Table G numbers are not included the NLM Classification Table G outline

Expanded Country Notation Examples

AM3	Maryland
AM3.1 M7	Montgomery County
AM3.2 B2	Baltimore

DC2.2 V2	Vancouver
FE5	England
FE5.1 M6	Middlesex
FE5.2 L6	London

The expanded country notation below for Australia is an example of how a cataloging agency may expand the notation of a state, country, etc. when the need arises. This kind of pattern can be used for any single country number
