Re:
Table 1. Standard Subdivisions
The accompanying PDF contains all updates to Table 1 approved by EPC since Meeting
124. These updates include an improved development for T1—072 Research and
T1—079 Competitions, awards, financial support; changes to the representation of
groups of people in T1—08 in the schedule and index; the revised caption at T1—09
History, geographic treatment, biography; extensions to collected biography; and other
minor updates.
In reviewing Table 1, we found minor wording changes to suggest in the records for
T1—068 and T1—0683. We also expanded the set of references in the T1—092 Manual
note to substantive discussions of biography elsewhere in the Manual, and addressed the
conflicting instructions at the end of the T1—092 Manual note. These changes are
summarized below, and included in the PDF. Not summarized below, but included in the
PDF, are the changes proposed in EPC Exhibit 131-21.1 with respect to T1—014,
T1—0141, and T1—03. We noticed when entering the record for T1—0141 that a
discontinuation note from Table 4 was accidentally carried over into the T1—0141 entry
in the aforementioned exhibit; the correct version of the T1—0141 entry is included in
the Table 1 PDF.
We also present one topic for discussion at the end of this paper: the provision for
T1—0286 Waste technology.

T1—068 Management
The change in wording in the class-elsewhere note at T1—068 was prompted by our
review of “in the sense of” during preparation of EPC Exhibit 131-7.1. The change in
wording in T1—0683 matches similar wording previously approved by EPC at 658.325.
—068
Management
Class management in the sense of carrying out ordinary activities
of subject a routine activity called management associated with a
profession, occupation, hobby in 001-999 without adding notation
068 from Table 1, e.g., management of patients 616 (not
616.0068); class interdisciplinary works in 658
See Manual at T1—068; also at T1—068 vs. 353-354
—068 3
Personnel management (Human resource management)
Including management of fringe employee benefits, of
in-service training and residency, of wages and salaries
Class comprehensive works on in-service training and
residency in –07155; class interdisciplinary works on labor
relations in 331.88
For management of executive personnel, see —0684;
See also 331.21 for wages; also 331.255 for fringe employee
benefits

Manual note at T1—092
We propose to add references to all substantive discussions of biography elsewhere in the
Manual.
We also propose to eliminate the section on “Approximating the whole” (the penultimate
section of the T1—092 Manual note) and revise the last section on “Biography associated
with place rather than subject.” Both sections were added in DDC 22 to replace
instructions under the “Division policies” section of the T1—092 Manual note found in
DDC 21. The instructions in the current “Approximating the whole section” are in
conflict with the general rules for the addition of standard subdivisions. Exceptions to
the general rule are treated in the note at 796.092 for sports, and in the revised last section
for biographies associated with place (plus in a longer discussion in the Manual note at
930-990: Biography).
Only the first section and the last two sections of the current Manual note at T1—092 are
shown below. The full Manual note with all changes incorporated can be found in the
Table 1 PDF.
T1—092
Biography
The following instructions apply also to notation 2 from Table 2 when
numbers from Table 2 are added directly without the interposition of
T1—09.
In the following notes the word "biography" is used for stylistic
convenience; however, the instructions apply fully to description and
critical appraisal as well as other aspects of treatment of individuals.
Do not use T1—092 for the actual works of a person except where
instructed to do so at certain numbers in 700-779.

Approximating the whole
Add T1—092 even in cases when a person's work may not approximate
the whole of the most specific available number. Conversely, do not add
T1—092 to extremely minute subjects, e.g., class ball players at the
number for game they played, not in subordinate numbers for specific
positions on the field, even if a player filled only one position.
Biography associated with place rather than subject
Class an individual biography in the number most nearly covering the
history and civilization of the place and time of the activity emphasized
when a work is not clearly associated with any subject but is clearly
associated with a place, even in cases when a person’s activity may not
approximate the whole of the most specific period, e.g., use 979.46104092
for the diary of a resident of San Francisco during the Gold Rush.

Discussion Topic: T1—0286 Waste technology
The provisions at T1—0286 Waste technology first caught my attention when I went to
address the following class-elsewhere note under T1—0288 Maintenance and repair:
“Class conservation in the sense of environmental engineering and waste technology in
—0286.” Since conservation and restoration are neither indexed nor mentioned at
T1—0286, I did not plan to propose adding see-also references to link the two records as
recommended in EPC Exhibit 131-7.1; I planned simply to delete the class-elsewhere
note from T1—0288.
However, upon further inspection of both records, I found some additional issues related
to the application of T1—0286, the mix of topics and relationships in T1—0286, and the
indexing of conservation and restoration (plus preservation) at T1—0288 and elsewhere.
All require additional investigation. A summary of the issues follows:

T1—0286 is currently referenced several places in the 600s and at
770.286. A quick survey of Dewey Section classifiers discloses
infrequent use of the standard subdivision, except to express green
technology.

The relationships expressed in T1—0286 are not the same as their
schedule equivalents. The caption at T1—0286, Waste technology,
corresponds to waste technology in 628.4 Waste technology, public
toilets, street cleaning. The topics in the class-here note at T1—0286,
environmental engineering and pollution control engineering, refer to
4
topics in 628 Sanitary and municipal engineering and 628.5 Pollution
control technology and industrial sanitation engineering, respectively.
Environmental engineering is not even mentioned at 628, but is indexed
to that number. The terms used at 628 are “environmental protection
engineering” and “environmental health engineering.” Both of these
topics are indexed, but T1—0286 is not associated with either index term.

The three topics in the class-here note under T1—0288 Maintenance and
repair—conservation, preservation, restoration—currently appear in the
Relative Index without qualifiers. “Conservation of natural resources” is
the Relative Index term associated with the environmental aspects of
conservation. The maintenance and repair aspects plus environmental
aspects of restoration are merged into a single index entry, Restoration.
The maintenance and repair aspects of preservation plus the preservation
of biological specimens are merged into a single entry, Preservation. We
are considering adding the qualifier “(Maintenance and repair)” to the
Relative Index entries for Conservation, Preservation, and Restoration.
We also are considering changing “Restoration—natural resources” to
“Restoration of natural resources” to match the entry “Conservation of
natural resources.” We are still investigating the best treatment for the
three subheadings under Preservation related to specimens—these are
really built from a special subdivision of T1—075 under 570.752 related
to Collection and preservation of specimens. They are already indexed
under the type of specimen with “preservation” as a subheading. Perhaps
adding a new entry, “Preservation of specimens,” with the types of
specimen as subheadings, is the best approach.
We will continue our investigation of these matters, and propose a solution at Meeting
131 for action at Electronic Meeting 131A. We welcome comments and suggestions in
advance of Meeting 131.
