Dewey Classification

 

Melvil Dewey (1851-1931) devised the library classification system known as Dewey Decimal Classification. many libraries all over the world, particularly public libraries, are classified by Dewey.

Dewey was a student at Amherst College, Massachusetts, when he devised his classification system and it was first adopted by the college library there. He became a founder of the American Library Association and the founder and first director of the New York State Library School.

Two other Americans devised library classification systems: Henry Evelyn Bliss and Charles Ammi Cutter, Bliss's Bibliographic Classification is used in some special libraries and Cutter's Expansive Classification is still used a little in the United States but hardly at all elsewhere.
