Relocations and Discontinuations
In Abridged Edition 15, relocation and discontinuation notes usually follow other types
of notes at the former location (the location from which a topic or group of topics has been
shifted) in the schedules and tables.
The following two lists show all the relocations and discontinuations since Abridged
Edition 14.
The column headed Edition 14 indicates in numerical order each number in that edition
from which a topic or group of topics has been shifted; the column headed Edition 15 indicates each corresponding number in the present edition to which those topics or groups of
topics have been shifted. If two or more topics have been shifted from one number to two
or more numbers, each separate shift is shown.
Numbers in the Edition 14 column enclosed in square brackets are no longer in use;
those not enclosed in brackets have lost part of their meaning through relocation or discontinuation, but still retain some of their original meaning.
In the following lists, the same abbreviations employed in the Relative Index are used
for Tables 1–4, e.g., T1 means Table 1 Standard Subdivisions.
Relocations
In a relocation, one or more topics are shifted to a number differing from the old in
respects other than length. If the relocation is partial, the original number remains valid;
but if it is total, the original number is no longer used. Relocations are described and
explained in the Introduction.
Relocations that have appeared previously in an interim update prior to publication of
Abridged Edition 15 are indicated by * next to the Abridged Edition 14 number. Relocations that eliminate dual provision for the same topic or topics are indicated by † next to
the Abridged Edition 14 number.
For example, one of the topics that was in 371.01 in Abridged Edition 14 has been relocated to 371.05 in Abridged Edition 15; all of the topics in [372.82] have been relocated to
372.37. All the topics in 608.72 have been relocated to 609.2 to eliminate dual provision.
Scattered within 305–306 means that the topic has been relocated to so many numbers
throughout that span that it is not feasible to name them all.
For details of the specific relocated topics the classifier should consult the appropriate
entries in the tables and schedules.

Discontinuations
A discontinuation is the result of shifting one or more topics to a number shorter than the previous one but otherwise not differing from it. If all topics in a given number are thus shifted,
the number is no longer valid. Discontinuations are described and explained in the Introduction.
For example [362.7086] has been discontinued and all of its contents moved up to the broader
number 362.7, while only some of the topics in 362.7085 have been moved up to 362.7.
For details of the specific discontinued topics the classifier should consult the appropriate
entries in the tables and schedules.
