• The future is now: DDC 23 in the big picture
Overview of DDC 23
DDC 23: A few highlights
• Major updates in religion (Islam and Orthodox
Christianity), law, education, food and clothing, graphic
arts, cinematography and videography, ancient and
modern world
• Overhaul of groups of people
• A host of new numbers (e.g., bullying, cloud computing,
end of Mubārak administration)
• Structural changes to support machine display and
retrieval, and classifier efficiency
DDC 23: Some themes and examples
• Groups of people
• Viewpoint
• Digital trends
• Types/styles
• Structure
Groups of People
Groups of people (1)
• “kinds of persons”  “groups of people”
T1—08 Groups of people
305 Groups of people
• “persons treatment”  “biography”
T1—09 History, geographic treatment, biography
Table 2 Geographic areas, historical periods, biography
Groups of people (2)
T1—081 People by gender or sex
T1—0811 Men
T1—0865 People by marital status
T1—0867 Transgender and intersex people
T1—0925–0928 New numbers for collected
biography of groups of people
Groups of people (3)
• Ripple effect of changes throughout DDC 23,
especially for groups of people in 155, 305–306,
331, and 362
• Reversal in preference order in 302–307 to
topic/group, e.g., friendship in women 302.34082,
not 305.4 Women

Summary
We’ve used the publication of DDC 23 as an opportunity to
look closely at the system in order to understand
• the key changes in the new edition
• the reasons behind the changes
• the complementary role of WebDewey in terms of
updates, additional content, and productivity tools
• the different representations of the DDC
• the place of DDC 23 in the Dewey ecosystem
