Melvil Dewey
1851-1931
• Librarian at Amherst College when he
developed the Dewey Decimal
Classification (DDC) system
• A Classification and Subject Index for
Cataloguing and Arranging the Books
and Pamphlets of a Library published
in 1876
• Original was 44 pages long
DDC today
 Four volumes
 Published every 8 years
Online version updated frequently
 Responsive to customer needs

Relative
Index
Two features introduced by
Dewey
• Relative location - Dewey system
numbers books in terms of their
relation to one another without
regard to the shelves or rooms where
they are placed 000
999
• Relative index - Brings together
under one term the locations in the
scheme of a subject which falls in
several fields of study
Two ways to find a number
in the schedules
 Summaries
 Front of schedules (Volume 2)
 Ten main classes
 Hundred divisions
 Thousand sections
 Relative index
 Last volume (Volume 4)
 Relates subjects to disciplines
The Dewey Decimal System
• Advantage: Orderly, hierarchical
system that organizes the
universe of knowledge
• Disadvantage: Based on the
decimal system. The real world
isn’t neatly divided into tens (e.g.
periodical table)
