The updated best practices feature a new module, "Demographic/Geographic: mapping LCSH heading qualifiers to 386 and 370 fields." This module provides mappings from qualifiers that describe demographic groups which appear in LCSH heading constructions (e.g., Cherokee poetry; Folk literature, Abkhaz; Gay men's writings) to their corresponding demographic terms (for use in a 386 field) and geographic place names (for use in a 370 field), along with recommendations for their implementation.
BACKGROUND:
The Retrospective Implementation of Faceted Vocabularies resource describes a set of best practices for implementers wishing to apply LC faceted vocabularies--using purpose-built fields in the MARC 21 bibliographic format--retrospectively to library catalogs, utilizing automated and semi-automated processes. It is also intended to serve as an ever-growing hub of information for all matters related to retrospective implementation of LC faceted vocabularies, including efforts undertaken by specialist communities of practice, library consortia/cooperatives, library systems vendors, etc. Lastly, it articulates a "roadmap" for ongoing work by SSFV and allied communities of practice.
This integrating resource is modular in nature and subject to dynamic, ongoing updates. Early versions of these best practices will be incomplete. The new demographic/geographic mapping module joins the other modules are available to implementers now:
-
Genre/Form: mapping MARC fixed field codes to 655 and 385 fields
-
Genre/Form: mapping LCSH form subdivisions (and select topical subdivisions) to 655, 385, 386 fields
-
Genre/Form: mapping LCSH music form headings to 655 fields (not SSFV's own work, but a brief description of and links to the Music Library Association's work)
-
Medium of Performance: mapping LCSH music form headings to 382 fields (not SSFV's own work, but a brief description of and links to MLA's work)
Three appendices contain links to resources for current implementation of faceted vocabularies, a bibliography of literature on display and indexing of faceted data, and a list of MARC fields incorporated in mapping modules.
SSFV anticipates updating and re-releasing the summary document periodically. However, the modules themselves are even more dynamic and subject to frequent updates, particularly as the LC vocabularies continue to grow and evolve. Implementers are advised to take into account the "last updated" date on each module when consulting that module; this date may be later than the "last updated" date on the summary document. Stay tuned for further updates to this resource!
