Library of Congress Classification System
The general book collection in the NMSU Library is organized on the shelves by subject using this classification system used by most academic libraries in the United States. (In addition most special collections in the NMSU Library- "Periodicals," "Reference," "Map and Atlas," and "Indexes and Abstracts" - all follow this same subject arrangement.) The Library of Congress Classification Outline (Library of Congress) gives a general overview of the entire classification system. Listed below are the major classification areas where range literature is likely to be found:
