The Library of Congress Genre/Form Terms for Library and Archival Materials (LCGFT) thesaurus includes a robust set of headings for cartographic resources, which were among the earliest areas of focus during LCGFT’s development. The first cartographic headings were approved for the thesaurus in 2010, as part of a cartography-specific project undertaken in consultation with the Library of Congress Geography and Map Division. Following that initial burst of activity, the suite of available terms for describing cartographic resources has been largely stable until recently, with the addition of a small number of new cartographic headings beginning circa 2023. In this report, I will share some observations on the application of LCGFT in my library’s catalog, including discussion of successes and challenges, drawn from my first ten years as a map cataloger at Michigan State University.
