Library of Congress Classification System

The interdisciplinary nature of geography requires the use of material from a variety of subject areas. This outline, which is part of the Geography site at The Mining Company should assist you to locate areas of the library to begin your research.

The LC System organizes material in libraries according to twenty-one branches of knowledge. The 21 categories (labeled A-Z except I,O,W,X and Y) are further divided by adding one or two additional letters and a set of numbers.
