Re: History notes in electronic editions

EPC Exhibit 135-28.1”New Models for Relocations and Discontinuations”, which was previously distributed as EPC Exhibit 128-39, contained the following proposal on how changes in the classification should be indicated:

Our current rules for presenting relocation and discontinuation information in captions and notes are tied to the print editions of the DDC. Captions and notes can carry relocation and discontinuation information for seven to fourteen years—relocations and discontinuations added after an edition has been published are included in the next edition, along with new relocations and discontinuations. Most changes are detailed in the tables of relocations and discontinuations associated with a new edition (“Table 8”); major changes are also described in “New Features.”

We are exploring a new approach to the handling of relocations and discontinuations in the DDC. Instead of inserting relocation and discontinuation information into captions and notes in individual records, we propose to develop a “show history” feature in WebDewey that will show the history of recent changes associated with a particular record using information harvested from the 685 fields (a MARC view will also be available to see the 685 fields in their raw state).

(Note: The “History” box is now part of WebDewey.)

The adoption of the new approach would also affect the presentation of relocation and discontinuation information in future print editions. The information would be available in the tables of relocations and discontinuations associated with a new edition (“Table 8”) and major changes would continue to be summarized in

1

“New Features.” If desired by users of the print edition, we could explore the development of an automatic process to include the relocations and discontinuations since the last print edition in individual records.

In order to implement this proposal, the Editorial Rules concerning changes to the classification, especially Section 2 “Procedures for development and corrections”, had to be revised. A summary of the major changes follows:1) New section 2.2 Order of multiple 685 fields

(We will reorder the 685 fields in the database that do not follow this order.)2) The sections covering various types of changes are arranged by the second indicator:

0 Relocation at old location1 Relocation at new location2 Discontinuation at old location3 Expansion at new location4 Discontinuation at new location5 Expansion at old location

The two discontinuation fields and the two expansion fields are given together in the same section of the Editorial Rules.

3) 685 fields for two new types of changes are introduced:Discontinuation at new location – with 4 as the second indicatorExpansion at old location – with 5 as the second indicator

(We would have preferred to use indications 2 and 3 for the two discontinuation fields but indication 3 was already used for expansion at the new location.)

4) The associated changes to the rest of the record based upon the type of change are now given. For example, Rule 2.3.5.1 gives the changes to the rest of the record when there is a complete relocation.

5) The examples follow these rules. Only 685 fields giving the changes made for Edition 23 will be revised to reflect these rules. 685 fields for changes made in previous editions will not be revised.

6) The wording indicating the various changes are now similar. For example, in previous editions the wording of the relocation note was “[Topic] relocated to [number]” and of the discontinuation note was “Use of this number for [topic]; discontinued to [number]. The wordings are now “[Topic] relocated to [number]” and “[Topic] discontinued to [number]”.

7) Previously, the information that a number was being immediately reused was only given as 4 in the first indicator of the 685 field. New rule 2.6.3.1 introduces a new 685 immediately reused field.

8) The formatted version of the 685 field is no longer given in Section 2. The new rule 9.22 History note indicates how the 685 field is formatted in WebDewey and provides suggestions on how the 685 field can be formatted if the decision is made to display it in the context of a class entry.

The complete Section 2, without strikethroughs or underlining is given in EPC Exhibit 137-7.1b.

2

The following are the parts of the other rules that are associated with the changes made in Section 2. Strikethroughs and underlining indicate the changes. Other rules (sometimes just the number and name of the rule) are given for context.

1 Kinds of development

1.1 Major revision: New schedule

1.1.1 The schedule has been completely reworked and has been removed to a new location, so that there is no conflict with the old schedule. An example of this is the 004-006 revision of Edition 19 a new schedule in Edition 23 is 777 Cinematography and videography.

1.1.2 Changes are usually shown through 685 relocation fields and comparative and equivalence tables rather than through relocation notes (see Comparative Tables; Equivalence Tables).

1.1.4 The location to which the new schedule is moved must have been vacant for at least one edition, i.e., the location of a new schedule for Edition 23 must have been vacant in Edition 22.

1.2 Major revision: Complete revision

1.2.2 Changes are usually shown through 685 relocation fields and comparative and equivalence tables rather than through relocation notes (see Comparative Tables; Equivalence Tables).

1.3 Major revision: Extensive revision

1.3.2 Changes are usually shown through 685 relocation fields and comparative and equivalence tables rather than through relocation notes (see Comparative Tables; Equivalence Tables).

1.4 Moderate and minor revisions

The old text is edited to conform to current rules and to include new changes and changes already distributed in electronic updates. The schedule undergoes revision with expansions, reductions, regularization of structure, and new terminology and wording. All changes are shown by the use of notes 685 fields. An example of a moderate revision is 004-006 Computer science in Edition 22.

3

1.5 Minor revision

The old text is edited to conform to current rules and to include new changes and changes already distributed in electronic updates.

(Note: Old rules 1.4 and 1.5 have been combined into new rule 1.4.)

4 Headings

Each heading usually consists of a word or phrase inclusive enough to cover all topics subordinate to it. Do not sacrifice clarity to achieve brevity. See 4.2 and 4.4 for departures from the norm.

See 2.3.5.1.2 for wording of headings of entries whose topics have been completely relocated, 3.2 for three-digit numbers and their headings, 9.14.2 for headings in tables of preference.

6 Add instructions

6.2 Parts of the add note

6.2.4 Examples

6.2.4.4 Relocations to or from the subject at the base number must may be shown through examples. The relocation may serve as the required example unless it is a trivial one.

In the following example, “conservatories (botanical research buildings)” was relocated from 728.924 to 727.558.

727.500 1–.599 9 Specific types of research buildings

Add to base number 727.5 notation 001–999, e.g., physics laboratories 727.553, conservatories (botanical research buildings) 727.558 [formerly 728.924], physics laboratories 727.553

153 ## $a 727.558 $e 727.55  $9 ess=ien685 21 $t Conservatories (botanical research buildings) $i formerly

located in $b 728.924  $d 20110401 $2 23

4

6.2.4.5 Relocations and revisions within the pattern schedule that do not affect the meaning of the subject at the base number are not shown.

For example, compare the add notes under 639.39 [Culture of] Reptiles, for which the pattern span was relocated and completely revised in Edition 19.

From Edition 18:

Add to 639.39 the numbers following 598.1 in 598.11-598.14, e.g., culture of snakes 639.392

From Edition 19:

Add to base number 639.39 the numbers following 597.9 in 597.92-597.98, e.g., culture of snakes 639.396

6.6 Exceptions to, discontinuations from, and relocations from add provisions

6.6.1 Topics provided for elsewhere

If a part of the subject developed in the pattern schedule has been separately provided in a schedule related to the base number, explain the exception by combining a see reference (see 9.16) with the add note, using the word "however." If multiple see references are needed, they are separated by ";" and arranged in numerical order.

629.132 523-.132 528 Piloting specific types of heavier-than-air aircraft

Add to base number 629.13252 the numbers following 629.1333 in 629.13333-629.13338, e.g., piloting helicopters 629.1325252; however, for comprehensive works on piloting airplanes, see 629.13252; for piloting commercial craft, see 629.1325216; for piloting private craft, see 629.1325217

If the exception cannot be simply stated, limit the span or spans covered by the add provision as instructed in 6.1.3.

See 6.6.4 for combination of relocations and topics provided for elsewhere, 6.6.5.3 for combination of standard subdivisions not used, relocations, and topics provided for elsewhere.

5

6.6.2 Relocations and discontinuations from add provisions

If part of the subject in the pattern span is being discontinued, explain the discontinuation by combining a discontinuation note (see 2.3) with the add note, using the word "however." Give both the old and the new location in the note. If multiple relocations are needed, they are arranged in the numerical order of the old numbers. See 6.6.4 for an example.

(Note: “Relocations and” is new to the heading.) 6.6.2.1 If a topic in the pattern span is either relocated or discontinued, the relocated

or discontinued topic can be given as one of the examples. See 6.2.4.4 for an example.

6.6.2.2 If a part of the subject developed in the pattern schedule has been relocated to another part of the classification, the topic is given in the “however” portion of the add note. See 6.6.1 for the however portion of an add note.

6.6.2.3 The relocation or discontinuation information is given in the 685 field in the entries at both the old and new numbers.

6.6.2.3.1 If the old number is vacated, the entry is a history entry. See 2.3.5.1 for things to do for entries with complete relocations, 2.4.3.1.1 for things to do for entries with complete discontinuations.

6.6.2.4 In the following example, “education of young people” was discontinued from 371.823 to 371.82, “education of boys” was relocated from 371.823 to 371.8211, and “education of girls” was relocated from 371.823 to 371.822.

371.821–.829 Subdivisions for specific groups of students; for schools for specific groups of students

Add to base number 371.82 the numbers following —08 in notation 081–089 from Table 1, e.g., education of females 371.822, education of students of specific ethnic or national origin 371.829; however, for students who are the focus of special education, delinquent and problem students, students with disabilities and illnesses, gifted students, see 371.9

6.6.3 Relocations from add provisions

If part of the subject in the pattern span is being relocated, explain the relocation by combining a relocation note with the add note, using the word "however." Give both the old and the new location in the note. If multiple relocations are needed, they are arranged in the numerical order of the old numbers.

Examples from Edition 22:

641.33–.35 Specific food from plant crops

Add to base number 641.3 the numbers following 63 in 633–635, e.g., legumes 641.3565; however, field legumes relocated from 641.333 to 641.3565

305.489 6 Women by social, economic, cultural level; special social status

Add to base number 305.4896 the numbers following —086 in notation 0862–0869 from Table 1, e.g., working class women 305.489623; however, single women relocated from 305.489652 to 306.8153; engaged women relocated from 305.4896523 to 306.734082; separated and divorced women relocated from 305.489653 to 306.893; widows relocated from 305.489654 to 306.883; married women relocated from 305.489655 to 306.8723; women by sexual orientation relocated from 305.48966 to 306.76; lesbians relocated from 305.489664 to 306.7663; unmarried mothers relocated from 305.4896947 to 306.87432; for women from nondominant religious groups, see 305.486; for women from nondominant ethnic and national groups, see 305.488; for women offenders, see 364.374; for women inmates of penal institutions, see 365.6082

See 6.6.4 for combination of relocations and topics provided for elsewhere, 6.6.5.3 for combination of standard subdivisions not used, relocations, and topics provided for elsewhere.

8

6.6.4 Combination of discontinuations, relocations, and topics provided for elsewhere

Give the discontinuation first, followed by the relocation. Separate each instruction by a semicolon. If multiple discontinuations or relocations are needed, arrange them in the numerical order of the old numbers. If multiple see reference are needed, arrange them in numerical order.

Examples from Edition 22:

641.63–.67 Cooking food derived from plant crops and domesticated animals

Add to base number 641.6 the numbers following 63 in 633–637, e.g., legumes 641.6565, meat 641.66, chicken meat 641.665; however, field legumes relocated from 641.633 to 641.6565; for ices, sherbet, sorbet, see 641.863

334.681 001–.681 999 Subdivisions for producer’s cooperatives in industries other than extractive, manufacturing, construction

Add to base number 334.681 notation 001–999 (but not 381–382), e.g., cooperative legal services 334.68134; however, cooperative marketing discontinued from 334.6813801–334.681382 to 334.6; cooperative marketing by producers in extractive, manufacturing, construction industries relocated from 334.6813801–334.68382 to 334.682–334.688; for banking and credit cooperatives, see 334.2

9

6.6.5 Standard subdivisions are not added

6.6.5.3 Combined with relocation and/or topics provided for elsewhere

Give the standard-subdivision instructions first, the relocation second, and the see reference last. Separate each instruction by a semicolon. If multiple standard-subdivision instructions are needed, they are arranged in Table 1 order. If multiple relocations are needed, they are arranged in the numerical order of the old numbers. If multiple see reference are needed, they are arranged in numerical order.

199 *Philosophy in other geographic areas

Add to base number 199 notation 4-9 from Table 2 for continent or country only, e.g., Mexican philosophy 199.72; however, do not add notation 09 from Table 1 for history, geographic treatment, biography; for Asian philosophy, philosophy of Arabic-speaking North Africa, see 181; for European philosophy, see 190; for comprehensive works on North American philosophy, see 191

9.19 Discontinued note

A discontinued note is used to indicate that a number from the preceding edition has either been moved back to a more general number or dropped entirely because it has become obsolete or without meaning in context. The most common usage is the moving back of a specific topic.

9.22 History note

The history note, the formatted version of the 685 field, gives information about changes to the classification. The types of changes are relocations, discontinuations, expansions, and immediately reuse of a number. See 2 for the various 685 fields of the changes.

Versions of the history notes for the following 685 fields are provided.

153 ## $a   305.556   $e   305.55 $j   White collar classes 685 20 $t   Office workers   $i   relocated to   $a   305.96513 $d   20110401   $2

20110401   $2   23

9.22.1 In WebDewey, the history note is given in the History box. For this formatted version, the text of the 685 field is given minus the subfield coding, hyphens separate the parts of the date, and the $2 is changed to Edition. Each note is given separately. The first word of each note is capitalized.

Use of this number for white collar workers discontinued; class in 305.55 2011-04, Edition 23

Office workers relocated to 305.96513 2011-04-01, Edition 23

Clerks relocated to 305.965137 2011-04-01, Edition 23

9.22.2 In a printed version of the English language DDC, information about changes to the classification is given in “New Features of the DDC”, lists of relocations and discontinuations, comparative and equivalent tables, and list of reused numbers, not in history notes.

9.22.2.1 A user who wants to give history notes must decide the formatting criteria for the note. One possible criterion is to use the format given in WebDewey. Another formatted version is based upon the print version of the previous relocation and discontinuation notes. For instance, if there is more than one 685 of the same type change, the notes are given in one paragraph and separated by a semicolon. If the first word of notes other than the first note are usually not capitalized, the first word in lowercased.
