General genre/form terms

  • General genre/form terms

    • Many genre/form terms do not belong to a particular discipline.
    • Project in the works to create genre/form terms for many current form subdivisions (185s). (E.g., Biographies, Bibliographies, Correspondence.)


Many aspects of what we may consider genre/form are out of scope for LCGFT.

  • Many aspects of what we may consider genre/form are out of scope for LCGFT.

    • LCGFT terms cannot be subdivided geographically.
    • Ethnicity, language, religion, chronology, and audience characteristics are also out of scope.


Many current subject headings acting as genre/form headings include these aspects

    • Many current subject headings acting as genre/form headings include these aspects
      • Examples
        • Jazz $z Lithuania
        • African Americans $v Music
        • Songs, German
        • Buddhist music
        • Rock music $y 1961-1970

The ALA Subcommittee on Genre/Form Implementation is working on finding places in the MARC record for these aspects.

  • The ALA Subcommittee on Genre/Form Implementation is working on finding places in the MARC record for these aspects.

    • MARBI discussion papers forthcoming.


Creating hierarchies for terms destined for LCGFT

  • Creating hierarchies for terms destined for LCGFT

  • Why hierarchies?

    • LCGFT is meant to be a true thesaurus
    • Each term should be linked hierarchically to at least one other term
    • This structure will enable new ways of utilizing broader and narrower terms
    • Illuminates aspects of vocabulary that need to be addressed




MARBI proposal at ALA Midwinter

  • MARBI proposal at ALA Midwinter

    • MARC Proposal no. 2012-01 (New Data Elements in the MARC21 Bibliographic and Authority Formats for Medium of Performance

      • Expanding field 382 (already established for medium of performance, but created as an RDA element)
      • Creating a new field for medium of performance


MARBI approved option 1 (draft):

      • 1st indicator: Display constant controller
      • # – No information

A sound recording with three works in different genres and for different mediums.

  • A sound recording with three works in different genres and for different mediums.

    • Using $8 to link the analytical entries to the genre/form and medium fields that correspond
      • NOTE: $8 has not currently been implemented outside of holdings records (that we know of).
    • Not an ideal solution, but until information coded in work records can be pulled into displays for compilations, we’ll need a workaround.




The same as always!

  • The same as always!

  • Until music genre/form terms are in LCGFT and the medium of performance thesaurus is available, continue to construct music subject headings in 650s.



What is involved in implementing music genre/form and medium of performance vocabulary?

    • Creation of genre and medium authority records
    • Updating authority files and maintenance
    • Conversion of existing headings
    • Indexing
    • Search interfaces


  • Are new fields needed in MARC authority format for medium?

  • Who will create the records?

  • Method

  • Non-music facets



Map the topically-coded LCSH authorized headings to new genre and medium authorized headings

  • Map the topically-coded LCSH authorized headings to new genre and medium authorized headings

  • Flip the topically-coded headings in bibliographic records to new genre and medium fields

  • This process will take some time, but it will eventually be completed



Reference record

  • Reference record

  • 1XX Sonatas (Marimba and piano)

  • 2XX $i Medium use $a marimba $n 1 $a piano $n 1 $s 2

Indexing

  • Indexing

    • The genre/form (655) and medium of performance (382) fields should be included in any index where genre and medium terms will be used to retrieve results.
  • Search interfaces

    • Determine if your institution includes a genre search in the public catalog.
  • What to do now

    • Communicate to other technical service and systems librarians at your institution how important genre and medium access is for music.


Improved access to music materials

  • Improved access to music materials

    • Direct access by medium of performance
    • Clearer and more specific vocabulary
  • Examples: What a faceted search might look like

    • Examples from the Media Finders created at Ball State University










Create authority records for new terms

  • Create authority records for new terms

  • Recommend system changes to accommodate terms (indexing, etc.)

  • Plan conversion of existing headings

  • Create best practices and training materials

  • Announce terms are available for use

  • Timeline 2012-2013?
