Melville Louis Kossuth "Melvil" Dewey was an influential American librarian and educator, inventor of the Dewey Decimal system of library classification, a founder of the Lake Placid Club, and a chief librarian at Columbia University. He was also a founding member of the American Library Association. Although Dewey's contributions to the modern library are widely recognized, his legacy is marred by allegations of sexual harassment, racism, and antisemitism.

The Dewey Decimal Classification (DDC), colloquially known as the Dewey Decimal System, is a proprietary library classification system which allows new books to be added to a library in their appropriate location based on subject. It was first published in the United States by Melvil Dewey in 1876. Originally described in a 44-page pamphlet, it has been expanded to multiple volumes and revised through 23 major editions, the latest printed in 2011. It is also available in an abridged version suitable for smaller libraries. OCLC, a non-profit cooperative that serves libraries, currently maintains the system and licenses online access to WebDewey, a continuously updated version for catalogers.
