1. The Dewey Decimal
Classification (DDC) system has a long history (127 years) of expansion and adaptation to the needs of the communities it
serves.
2.
Aspects of the DDC
are being developed and maintained by the Library of Congress.
3. The DDC is published in both full and abridged versions, as well
as, now, online versions of the full and abridged editions in a format
called ‘Web-Dewey.’
4.
The DDC uses very well recognized Arabic numerals and the numbered notation makes it easily understandable from one culture to
another.
5. The DDC has bi-weekly updates to its current edition put out
online.
6. The DDC breaks down into relatively well structured and ordered
disciplines, divisions, and sections.
7. The DDC is used by over 200,000 + libraries
in 135 countries
around the world.
8.
Extensive efforts have been continuously made to correct
American/Protestant biases since the 16th Edition released in
1958.
9. Through the use of MARC 21, OCLC, and LC records it has become a
simple matter to determine DDC numbers through either CIP and/or copycat
cataloguing of records.
10. The DDC is constantly undergoing revisions. (Note: This can also
be considered a flaw.)
11.
The DDC system is infinitely expandable.
