Please tell me if you can locate helpful text, illustrated with
concept maps and/or diagrams, to explain the complete Dewey Decimal
Classification System. I have searched under "Dewey classification AND
diagram" and obtained a couple of useful "hits" but they were geared
at teaching young children parts of the system. I need information
that covers the complete Dewey classification system.

Request for Question Clarification by bethc-ga on 29 Aug 2003 18:49 PDT

I have found a site that has a diagram depicting each of the major
divisions of the Dewey classification system and its topic:

000s Computers and Information Science
100s Philosophy & Psychology
200s Religion
.
.
.
900s Geography & History



If you roll your cursor over each major division, its subdivisions
appear. For instance, under the 100s you would find:

110 Metaphysics
120 Epistemology, humankind
.
.
.
190 Modern western philosophy

Is this the kind of a diagram you are seeking, or are you looking to
have those subdivisions broken down even further? Also, this would not
be a diagram that you could easily print out, as it changes as you
roll your cursor over each major topic.

Clarification of Question by driller1-ga on 29 Aug 2003 19:25 PDT

The site you mentioned would be helpful but sounds as if it does not
provide quite the level of detail I would like. I am trying to teach
myself the intricacies of the Dewey decimal classification system and
the concepts of notation, citation order and building of numbers. I
would find it very helpful to have explanatory diagrams in the
resource - not just the text as per the Dewey Manuals. Hope this
helps. Thanks for asking.

There are several books, mostly used by library catalogers and
students of library science that offer completely detailed
explanations of the dewey decimal call number system:

Dewey decimal classification and relative index   / Melvil Dewey

Dewey decimal classification, 21st edition : a study manual and number
building guide /  Mona L. Scott

Dewey decimal classification, 19th edition : a study manual /  by
Jeanne Osborn

As far as on the web the authority on the Dewey Decimal Classification
system is OCLC's "Dewey Decimal Classification" homepage:

http://www.oclc.org/oclc/fp/index.htm

It is filled with tutorials and summaries.  This website brought me
here:

http://acad.cl.uh.edu/edu/slo/cat/catbut07.htm#DEWEY

The links to the summaries do not work but will bring you to a search
box where you can search for various elements of the dewey system:

http://www4.oclc.org/

This may be of help:

Thanks for the direction to the official Dewey site with which I am
familiar. I'm still looking for in depth diagrammatic illustrations to
connect with the text to teach the concepts. I have a workbook on the
13th Abridged Edition but the self-paced teaching style in it is full
of shortcomings - hence my request on Google!
