Harvard Spectral Classification Scheme

"The modern stellar spectral classification scheme (also known as the Harvard Spectral Classification Scheme) was created by Annie Jump Cannon through her examination of spectra from 1918 to 1924. Originally, the scheme used capital letters running alphabetically, but was later reordered to reflect the surface temperatures of stars. In order of decreasing temperature, these types were O, B, A, F, G, K and M. Three additional categories also in the scheme: R, N, and S types, were later realized to represent stars with peculiar heavy-metal abundances.

Cutter Expansive Classification

"Charles Ammi Cutter (1837–1903), inspired by the decimal classification of his contemporary Melvil Dewey, originally developed his own classification scheme for the collections of the Boston Athenaeum, at which he served as librarian for two dozen years. He began work on it about 1880 and published the first schedules in the early 1890s. His five-volume catalogue of the Athenaeum collection is a classic in bibliographic history.

Library Classification

"There are already in the field many rival schemes of classification for libraries. The present publication is not intended to add one to the number, but rather to offer a way of escape for those who shrink from the intricacies and difficulties of the elaborate systems, and to substitute for painstaking analytical classification a simple arrangement which it is believed is better adapted to be practically useful in a library, while doing away with most of the work involved in carrying out one of these schemes."

Harvard-Yenching Classification

"In 1931, the growing collection was transferred from Widener Library to the Harvard-Yenching Institute, founded in 1928. By the time of his retirement in 1964, [Alfred Kaiming] Chiu had built the library into a resource of hundreds of thousands of publications and an unparalleled collection of rare books and manuscripts. He also devised the first successful system for cataloging books in Chinese and Japanese. Known as the "Harvard-Yenching Classification System," it was adopted worldwide and remained in use for the next 40 years."
