Have we made a decision about mapping ‘locally assigned’ MARC fields?
OCLC provides special fields for “local bibliographic data” (LBD). “LBD is local information that complements the full bibliographic data in the WorldCat database. Enhance the bibliographic record for local use by adding local subject headings, uniform titles, or notes.”
This data is not retained in WorldCat but can be found in library databases
https://help.oclc.org/Metadata_Services/WorldShare_Record_Manager/LBD/Work_with_local_bibliographic_data?sl=en
Here are the LBD fields that are used in OCLC, as provided at https://www.oclc.org/bibformats/en/about/specialcataloging.html#localinformationinrecords. In the following fields, OCLC says it is valid to add ‘local data’:
Leader/05, 001, 004, 005, 240, 500, 501, 590, 591-598, 599, 600, 610, 611, 630, 647, 650, 651, 655, 690, 691, 695, 696, 697, 698, 699, 700, 710, 711, 730, 790, 791, 792, 793, 796, 797, 798, and 799.
Note that the input standards for the OCLC defined local fields mimic the instructions for the MARC21 fields to which they correspond, e.g., 690 corresponds to 650 and 790 corresponds to 700.
My question is, should we map locally assigned data from fields that are specifically designated by OCLC to carry such data, i.e., the X9X fields?
• 590 Local Note
• 591-598 Local Note
• 599 Differentiable Local Note
• 690 Local Subject Added Entry--Topical Term
• 691 Local Subject Added Entry--Geographic Name
• 695 Added Class Number
• 696 Local Subject Added Entry--Personal Name
• 697 Local Subject Added Entry--Corporate Name
• 698 Local Subject Added Entry--Meeting Name
• 699 Local Subject Added Entry--Uniform Title
• 790 Local Added Entry--Personal Name
• 791 Local Added Entry--Corporate Name
• 792 Local Added Entry--Meeting Name
• 793 Local Added Entry--Uniform Title
• 796 Local Added Entry--Personal Name
• 797 Local Added Entry--Corporate Name
• 798 Local Added Entry--Meeting Name
• 799 Local Added Entry--Uniform Title
I have included the 59X fields for consistency, but my main interest is in the 69X and 79X fields.
Note that this is somewhat related to the discussion about $5 at: #361
