NAME: Make Subfield $o in Fields 854-855 Obsolete
SOURCE: Library of Congress
SUMMARY: This proposal suggests making subfield $o in fields 854-855 obsolete in the USMARC holdings format
KEYWORDS: Field 854 (Holdings); Field 855 (Holdings); Definition of Enumeration and Chronology (Holdings)
DATES STATUS/COMMENTS
5/5/89 - Forwarded to USMARC advisory group for discussion at the June 1989 MARBI meeting.
6/27/89 - Results of USMARC advisory group discussion - Deferred. This issue needs to be studied further. There was a request for modeling of examples.
7/26/89 - Results of LC review - Agreed with the MARBI decision.
6/26/90 - Results of USMARC advisory group discussion - The issue of recording a supplement or index designation used as caption was subsumed under proposal 89-8/5, which was approved (Option C). Any remaining issues, including the use of subfield $o, will be reexamined in another proposal with a new number if necessary.
8/8/90 - Results of final LC review - Agreed with the MARBI decision.
PROPOSAL NO.: 89-8/7: Make Subfield $o in Fields 854-855 Obsolete
1. INTRODUCTION
Both the NISO serial (Z39.44, section 8.5.2.2) and the NISO non-serial (Z39.57, section 4.5.6.6.5.) standards provide for recording non-serial supplements, indexes, etc. having numbering relating to a part of a bibliographic unit (e.g., a multipart or serial item). In both cases, the caption and enumeration for the supplement, etc. are treated as a subsequent order designator, e.g.,
| Z39.44: | v.l6 : suppl.l (1977 : June 1) |
| v.3l : suppl. | |
| Z39.57: | v.3 : suppl. |
| v.3 : suppl. : pt.1\v.3 : suppl. : pt.2 |
Currently, the holdings format specifies that the designation for the supplement, etc. be recorded in subfield $o (Type of supplement/accompanying material) of field 854 (Definition of Enumeration and Chronology/Publication Pattern for Supplements/Accompanying Material) or in subfield $o (Type of index) of field 855 (Definition of Enumeration and Chronology/Publication Pattern for Indexes), although the full implications of coding in this way are unclear. (See Attachment A for the content designators valid for field 854; see Attachment B for the content designators valid for field 855.)
Display: v.3l : suppl.
| 854 | 10 | $6l$av. $osuppl. |
| 864 | 40 | $61.1$a31 |
| Note: Can the proposed display be generated from these fields? |
Display: v.l6 : suppl. l (1977 : June 1)
| 854 | 10 | $6l$av.$osuppl. |
| 864 | 40 | $6l.1$al6$bl$il977$jJune 1 |
| Note: The holdings format does not show an 854 subfield $o linked with an 864 subfield $b and the question arises as to whether the two subfields should be so linked. |
It seems that such supplement, index names should be treated as captions or as substitutes for a level of enumeration as the NISO serial and nonserial standards do and thus be coded in subfields $a-$f of the appropriate field 854/855. Consequently, the supplements, indexes to parts would be coded in a way more consistent with the NISO standards (i.e., as part of the caption) and with the way that basic bibliographic items are coded and displayed. Subfield $o in fields 854 and 855 could thus be made obsolete.
1) Display: v.l6 : suppl. l (1977 : June 1)
| 854 | 00 | $61$av.$bsuppl. |
| 864 | 40 | $6l.l$al6$bl$il977$jJune 1 |
2) Display: v.3l : suppl.
| 854 | 00 | $61$av.$bsuppl. |
| 864 | 40 | $61.l$a31 |
| Note: Display logic should output the 85X caption alone if there is no corresponding enumeration or chronology in the corresponding 86X field. Alternately, a convention for "null enumeration" could be developed, e .g., | ||
| 854 | 00 | $61$av.$bsuppl. |
| 864 | 40 | $6l.l$a3l$b( ) |
| Note: Empty brackets are used in 864 subfield $b for "null enumeration" so that the caption can be displayed alone. |
3) Display:
v.3 : suppl. : pt.1
v.3 : suppl. : pt.2
| 854 | 00 | $61$av.$bsuppl.$cpt. |
| 864 | 41 | $61.1$a3$c1 |
| 864 | 41 | $61.2$a3$c2 |
| or | ||
| 854 | 00 | $61$av.$bsuppl.$cpt. |
| 864 | 41 | $61.l$a3$b( )$cl |
| 864 | 41 | $61.2$a3$b( )$c2 |
| Note: In the second instance, empty brackets are used in subfield $b of field 864 for "null enumeration." |
2. PROPOSED CHANGES
The following is presented for consideration:
In the USMARC holdings format, make the following changes:
Note: The need to retain subfield $o (Name of supplement/accompanying material) in field 864 (Enumeration and Chronology--Supplements/Accompanying Material) and subfield $o (Name of index) in field 865 (Enumeration and Chronology--Indexes) should be investigated.
