Disclaimer

DATE: May 27, 2011
REVISED:

NAME: Identifying the Source of Thematic Index Numbers in Field 383 in the MARC 21 Authority and Bibliographic Formats

SOURCE: Music Library Association

SUMMARY: This paper proposes the addition of subfields $d (Thematic index citation code), $e (Publisher associated with serial or opus number) and $2 (Source code) in field 383 (Numeric Designation of Musical Work)

KEYWORDS: Field 383 (AD, BD); Numeric Designation of Musical Work (AD, BD); Thematic index numbers (AD, BD)

RELATED: 2010-04 (Section 3.5)

STATUS/COMMENTS:
5/27/11 - Made available to the MARC community for discussion.

06/26/11 – Results of MARC Advisory Committee discussion: Approved as amended. Rename subfield $d "Thematic index code" and redefine it as "Code identifying thematic index represented by number recorded in $c". Remove reference to $a in the definition of subfield $e and remove reference to $c in the definition of subfield $2.

07/19/11 - Results of LC/LAC/BL review - Agreed with the MARBI decision.


Proposal No. 2011-09: Identifying the Source of Thematic Index Numbers in Field 383

1. BACKGROUND

RDA has allowed for much greater granularity with authority record data, which in turn has led to the creation of new MARC fields to accommodate this data. One of those fields is the 383 - Numeric Designation of Musical Work (defined in Proposal No. 2010-04), which allows for the coding of a serial number, opus number, or thematic index number to help differentiate a work from among others with the same title. Since the field is repeatable, it can also cover multiple numbering and thematic indexing schemes for a single work.

As currently constructed, Field 383 allows for the inputting of all thematic indexes and numbering schemes associated with a unique composition. However, the field currently does not allow for the coding of data associated with the source of the thematic index numbers, or for clarification between different serial and opus numbers that represent a single composition when different indexes for the same composer used different numbering schemes.  Additionally, in recent discussions, the music cataloging community saw the creation of these new data elements as obviating the need to consult, or create new editions of, certain reference sources with thematic index numbers during the cataloging process.

During the discussion of 2010-04, MARBI removed subfield $2 from the final proposal, as no authoritative compilation of citations for thematic indexes existed. However, the Music Library Association (MLA) recently developed such a list, Thematic Indexes Used in the Library of Congress/NACO Authority File, which includes the composer’s name, a bibliographic citation for the thematic index, the authorized abbreviation for the thematic index numbers, and a citation code.

2. DISCUSSION

2.1. Current definition of Field 383

Field Definition and Scope:
A serial number, opus number, or thematic index number assigned to a musical work by the composer, publisher, or a musicologist. May be used to differentiate a musical work from another with the same title or to provide additional information.

2.2. Expanding 383 to include source of thematic index number

While field 383 allows for recording thematic index numbers associated with a musical composition, no mechanism exists for associating those numbers with a particular source. Outside of a specific context, “K.” could represent Köchel (for the composer Mozart), Kenton (Gabrieli), Kirkpatrick (Scarlatti), or several others.

This proposal suggests adding a new subfield $d (Thematic index citation code), as established in the Music Library Association’s thematic index source list Thematic Indexes Used in the Library of Congress/NACO Authority File (http://bcc.musiclibraryassoc.org/BCC-Historical/BCC2011/Thematic_Indexes.htm).

Implementing this subfield also requires establishing subfield $2 (Source of term) to specify the source of the code in subfield $d and creating a value to refer to the new MLA source list.

2.3. Different serial or opus numbers for same composition

There are situations where different publishers assign different opus numbers to the same work, or when different publishers assign the same opus number to different works.  To sort out these differences, this proposal suggests the creation of $e (Publisher associated with serial or opus number).  The subfield itself would not have controlled content.

3. EXAMPLES

Example 1:

For Vivaldi’s Four Seasons (a composition in four movements), exemplifying the use of $d and $2.

100 1# $a Vivaldi, Antonio, $d 1678-1741. $t Cimento dell'armonia e dell'inventione. $n N. 1-4
383 ## $b op. 8, no. 1-4
383 ## $c RV 269 $c RV 315 $c RV 293 $c RV 297 $d ryom $2 [code for the thematic index list]
383 ## $c F. I, 22-25 $d fanna $2 [code for the thematic index list]

Notice that the occurrence of the 383 with opus numbers does not contain any of the proposed data, as these fields apply almost exclusively to thematic index numbers

This example also exemplifies a composition identified differently by various thematic catalogs, i.e., described with a range of consecutive numbers in the Fanna thematic catalog, but with disparate numbers in the Ryom thematic catalog.

Example 2:

The next example demonstrates coding for the same composition identified with two different opus numbers assigned by different publishers:

100 1# $a Gyrowetz, Adalbert, $d 1763-1850. $t Serenades, $m clarinets (2), horns (2), bassoon, $n op. 3 (André)
400 1# $a Gyrowetz, Adalbert, $d 1763-1850. $t Serenades, $m clarinets (2), horns (2), bassoon, $n op. 5 (Hummel)
383 ## $b op. 3 $e André
383 ## $b op. 5 $e Hummel

Example 3:

An example qualified by two different publishers who assigned the same number to two different compositions.

100 1# $a Cambini, Giuseppe Maria, $d 1746-1825. $t Duets, $m flute, violin, $n op. 20 (Bland)
383 ## $b op. 20 $e Bland
100 1# $a Cambini, Giuseppe Maria, $d 1746-1825. $t Duets, $m flute, violin, $n op. 20 (LeDuc)
383 ## $b op. 20 $e LeDuc

4. PROPOSED CHANGES

Define the following subfields in Field 383 in the MARC 21 Authority and Bibliographic Formats:

$d – Thematic index citation code (NR)
Brief name identifying thematic index represented by number recorded in $c.

$e – Publisher associated with serial or opus number (NR)
Brief identification of publisher associated with number recorded in $a or $b. Used only where different publishers assigned different opus numbers to the same work, or when different publishers assign the same opus number to different works.

$2 – Source of code (NR)
Specifies the source of the code that identifies the thematic index cited in subfield $d and the citation patterns as found in $c . If a source code is needed for both data elements repeat the field.
