Charles Ammi Cutter

Charles Ammi Cutter (March 14, 1837 – September 6, 1903) is an important figure in the history of American library science.

In 1856 Cutter was enrolled into Harvard Divinity School. Cutter was appointed assistant librarian of the divinity school while still a student there. Throughout the development of his curriculum, Cutter was appointed assistant librarian (in which capacity he served from 1857-1859) and began designing a distinct cataloging schema for the library's outdated system. The catalog, dating from 1840, had a lack of order after the recent acquisition of 4,000 volumes from the collection of Professor Gottfried Christian Friedrich Lücke of University of Göttingen, which added much depth to the Divinity School Library's collection. Along with classmate Charles Noyes Forbes, Cutter rearranged the library collection on the shelves into broad subject categories during the 1857-58 school year. During the winter break of 1858-59, they arranged the collection into a single listing alphabetically by author. This project was finished by the time Cutter graduated in 1859. In 1860; a year after graduation, Cutter was already a seasoned staff member of the library and now a full-time librarian where he became a journeyman to the chief cataloger and assistant librarian Dr. Ezra Abbot. Cutter worked as a librarian at Harvard College where he developed a new form of index catalog, using cards instead of published volumes, containing both an author index and a "classed catalog" or a rudimentary form of subject index.

Cutter's career ascended in 1868 when the Boston Athenæum library elected him as its head librarian.
