Proposal No. 2017-06: Adding Subfields $b, $2, and $0 to Field 567


Field 567 is currently defined in the Bibliographic format as follows:

Field Definition and Scope:
Information concerning significant methodological characteristics of the material, such as the algorithm, universe description, sampling procedures, classification, or validation characteristics.

The note is sometimes displayed and/or printed with an introductory term that is generated as a display constant based on the first indicator value.


The National Library of Finland proposes adding subfield $b (Controlled term), subfield $2 (Source of term), and subfield $0 (Authority record control number or standard number) to the field 567 (Methodology Note).  The original proposal comes from the Finnish working group of subject indexers.

Using authorized terms from authorized thesauri or ontologies standardizes the practice of the note. The working group has recommended using the methodology terms from the Finnish subject thesaurus YSA or its Swedish translation Allärs. This is a common practice in Finnish university libraries today. It would be important and useful to be able to express this officially, using a proper subfield and the source code. Subfield $0 is important in identifying and linking the terms.

In 567 it is possible to describe the methodology in detail in subfield $a, using free text. But the idea of giving one term and its source should also be possible. This is also important for linking data. To separate the methodology free text note and the controlled term, a new subfield $b for the term is useful. In MARC 21, there are subfield $2’s in some note fields. 506, 518, 524 and 583 are good examples.

Creating a new field (3XX) might be an alternative. However, 567 is already a methodology field and by this addition it could be used more effectively.


Example 1

245 00 $a Die ägyptische "Ich-Erzählung" : $b eine narratologische Untersuchung / $c Claudia Suhr.
567 ## $b narrativ forskning $2 allars $0 <URI/ID>
567 ## $b Narrative inquiry (Research method) $2 lcsh $0 <URI/ID>
567 ## $b narratiivinen tutkimus $2 ysa $0 <URI/ID>

Example 2

245 00 $a Mozart's variations reconsidered : $b four case studies (K.613, K.501, and the finales of K.421 (417b), and K.491) / $c Esther Cavett-Dunsby.
567 ## $b Schenkeranalys $2 allars $0 <URI/ID>
567 ## $b Schenkerian analysis $2 lcsh $0 <URI/ID>
567 ## $b Schenker-analyysi $2 ysa $0 <URI/ID>

Example 3

245 00 $a Inefficiencies of quasi-market solutions from an institutional perspective : $b a qualitative case study comparison of local public transportation in six cities in Germany and Finland / $c Torsten Seidel.
567 ## $b fallstudie $b jämförande forskning $b kvalitativ forskning $2 allars
567 ## $b Case studies $b Comparative studies $b Qualitative research $2 lcsh
567 ## $b kvalitatiivinen tutkimus $b tapaustutkimus $b vertaileva tutkimus $2 ysa


Currently the BIBFRAME 2.0 has property natureOfContent which is where this information would be recorded.  It has a range of literal.  To accommodate this change the BIBFRAME 2.0 would need to change the range to a resource so that a controlled list and in particular a specific value from a controlled list may be indicated via a URL.


In field 567 (Methodology Note) of the MARC 21 Bibliographic format define the following subfields:

$b - Controlled term (R)
Index term to describe the methodology used in the material is from a controlled subject heading system or thesaurus.

$2 - Source of term (NR)
MARC code that identifies the source of the term used to record the methodology in subfield $b.

$0 - Authority record control number or standard number
See description of this subfield in Appendix A: Control Subfields.
