Cataloging Cartographic Materials

Subject Cutters

Library of Congress Classification (LCC) is a classification system that was first developed in the late nineteenth and early twentieth centuries to organize and arrange the book collections of the Library of Congress. The third edition of LCC (released in 1954) was the first to include a full classification scheme for maps. Cartographic materials are now cataloged in the "G" classification schedule, including atlases (G1000-3122), globes (G3160-3171), and maps (G3180-9980). Items are sub-arranged by designated regions, counties, cities, localities, etc. within the G classification schedule, with what is referred to as a "geographic Cutter." A full list of geographic Cutters can be found on ClassWeb Plus and is linked to on the Geographic Cutters page.

The Geography and Map Division maintains and develops a list of subject Cutters for further sub-classification of the specific content of a cartographic item. These subject Cutters are appended to the classification number following the geographic Cutter. The subject Cutters are found below.
