Proposal 2005-06 (Addition of Subfields for Relator Terms/Codes for Subject Access to Images) was presented for review and discussion in June 2005. The paper proposed defining subfield $e in fields 630 and 651 and subfield $4 in fields 630, 650, and 651 in the Bibliographic format so that relator codes and terms could be used to enhance the retrieval of visual materials. It was noted that field 611 had a subfield $4 for relator codes, but that subfield $e was already defined (as "Subordinate unit"). A suggestion was made to consider defining a different subfield in the 611 field for relator terms. This paper considers two options.
Option 1: Define new subfield for relator terms
While subfield $e has generally been used for the relator term, this subfield has already been defined as "Subordinate unit" in X11 fields. Consequently, one option is to define another subfield for relator terms. Available subfields are: $i, $j, $m, $o, $r, and $w. Subfield codes $m, $o, and $r are defined in the X00, X10, and X30 fields for music related information, and $i and $w are the only subfields not defined in any of the heading fields (so should be left for a need across all those fields). Therefore, if a new subfield were defined, subfield $j would be the best candidate. Code $j has a specialized use in the X00 field that is not applicable to the X11 field.

Option 2: Redefine obsolete subfield
Another option is to redefine subfields $b and $e in the X11 fields. Subfield $b (Number) was made obsolete in 1980. Any data currently in subfield $b could be moved to subfield $n (Number of part/Section of a work) where it has been since $b was made obsolete. Any data in the current subfield $e could be moved to $b, which would be redefined as "Subordinate unit." Selecting this option would also have the benefit of bringing X11 fields more into line with the structure of other name and subject heading fields in the formats.

If this option were selected there would be some effort involved in moving data, but there are relatively few occurrences of either subfield $b or subfield $e in X11 fields. Some statistics on occurrences in Library of Congress files are the following:
NACO Name authorities (6,279,130 records):
Subfield b: 84 occurrences in the 111, 411, 511, and 711 fields
Subfield e: 1,719 occurrences in the 111, 411, 511, and 711 fields
Books Bibliographic records (9,032,077 records)
Subfield b: 9,089 occurrences in the 111, 411, 611, 711, and 811 fields
Subfield e: 1,539 occurrences in the 111, 411, 611, 711, and 811 fields
