The vocabularies consist of:
- Library of Congress Genre/Form Terms for Library and Archival Materials (LCGFT), a faceted thesaurus designed to describe what a work is, as opposed to what a work is about.
- Library of Congress Medium of Performance Thesaurus (LCMPT) to describe the "medium of performance" (instrumentation, scoring, etc) for musical works/expressions.
- Library of Congress Demographic Group Terms (LCDGT) developed to capture the "category of persons who created or contributed to a work or expression and the intended audience for a resource".
For each vocabulary, the document provides general and specific recommendations for implementation. For example, it is recommended that addition of LCGFT terms become a core requirement for PCC BIBCO records wherever appropriate; specific recommendations for updates to documentation and manuals is outlined.
Application of LCMPT, LCGFT, and LDCGT descriptive elements to authority records is explored. Addition of data from these vocabularies to authority records would enable the possibility of this data being entered once instead of repeated entry in records describing different manifestations.
In conclusion, the paper argues for full-scale implementation of these new vocabularies, with a recommended suite of actions:
- Comprehensive faceted vocabulary training for catalogers working in shared environments
- Routine creation of work-level authority records for works "embodied in or likely to be embodied in multiple manifestations"
- Retrospective implementation of faceted vocabulary terms using algorithms
- Display and granular indexing of all faceted data in bibliographic records (MARC 046, 370, 382, 385, 386, 388 and 655)
- Display and granular indexing of authority data in specific fields.
