Benefits of an “abridged” view

• Access to the full content of DDC 23 class records

• Expanded Relative Index

• Expanded mapped terminology


• Abridged WebDewey in Connexion

• Sears

• LC subject headings applied to children’s materials (“SHC”) +

LCSH mapped to DDC numbers at the same level of notation

• WebDewey

LCSH

BISAC

MeSH

Access to mapped terminology


• Current segmentation practice is focused on addition of

segmentation marks to full numbers, not direct

assignment of abridged numbers by users of the abridged

edition

• Table 3 is a single table in the abridged edition, and split

into three tables (A-C) in DDC 23; Tables 5 and 6 are not

included in the abridged edition

• There is no easy way to indicate abridgment in the

Manual

Some challenges of an

“abridged” view of WebDewey


Segmentation options


• Segmentation marks (/) indicate the end of an Abridged Edition

15 number within a DDC 23 number in WebDewey

• If A15 number and DDC 23 numbers are the same, no

segmentation mark is given

• Segmentation marks are indicated in standard numbers

associated with individual class number entries (including

entries in tables), and in examples in segmentation instruction

notes

• Segmentation marks may be accompanied by segmentation

instructions
