Dewey 23
Many small ‘tweaks’ to numbers, rather than major areas of change
Many of these small changes have already been incorporated into WebDewey 22
Take great care when using numbers taken from other records, especially if these are Dewey 22 rather than 23. Always check numbers, rather than assuming that a number is correct
Example of change already added to WebDewey 22 (but not in the print manuals)
Main kinds of change
Topic moved to a new number
Changes to the scope of a number
New “add tables”
Changes to both scope and number
New historical periods
Topic shifted to a new number
Change to the scope of a number
New Add Tables
“Add tables” are lists of special notation that can be added to a base number to make it more specific. Dewey 23 contains some new add tables
For example, there is a new add table at 155 Differential and developmental psychology
Top 20 Teens: Discovering the Best-Kept Thinking, Learning & Communicating Secrets of Successful
Teenagers.
Top 20 Teens …
Class at: 155.51/9 Applied psychology for young people twelve to twenty
The breakdown is:
155.51 General topics of psychology of young people twelve to twenty plus 9 Applied psychology from the add table at 155
In Dewey 22, you do not have the option of adding 9 for “Applied psychology” so your number would just have been 155.51
Number moved and scope updated
Numbers that just don’t exist any more 721[.046] Architecture and the
environment, multiple-purpose buildings
Both the subordinate topics “Architecture and the environment’ & “Multipurpose buildings” have been moved elsewhere – so there is now no purpose for 721.046 and it has been removed
New historical period numbers added
Some areas where there have been many small changes 320s - Politics 363-363 - Social problems and services 808s – Collections of literary texts from more
than 2 literatures Historical period numbers for Italy and
SouthEast Asia New historical period numbers added for many
countries
Summary
Many small differences Ability to create more precise numbers (in
some cases) Always check numbers, and read scope
notes carefully
