Sears List of Subject Headings

"Since the first edition in 1923, the Sears List has served the unique needs of small and medium-sized libraries, suggesting headings appropriate for use in their catalogs and providing patterns and instructions for adding new headings as they are required. The successive editors of the List have faced the need to accommodate change while maintaining a sound continuity. The new and revised headings in each edition reflect developments in the material catalogued and in the use of the English language, aiming always to make library collections as easily available as possible to library users."
