    Benefits of an abridged view

    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

  • The worlds libraries. Connected.

    Segmentation options

  • The worlds libraries. Connected.

    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

    Segmentation marks are not currently indicated in the

    numbers associated with the following types of entries:

    Centered entry numbers

    Optional numbers

    Numbers in headings, notes (other than segmentation

    instruction notes), and references
