We currently load authority records into FOLIO and use this to clean up specific MARC values on our records such as author, series, and subject heading.
Authority sources include: LC Name Authority file (LCNAF), LC Subject Headings (LCSH), LC Genre/Form Terms (LCGFT), Faceted Application of Subject Terminlogy (FAST)
We currently have Backstage add URIs to the 1xx (authors), 6xx (subjects), 7xx (authors), and 8xx (series titles) MARC fields.
We do not add these fields to batch-loaded eResources.
We might have URIs in other fields that have been brought in when cataloging from OCLC, but our focus has been on URIs in those four groups of headings.
For some subject headings as decided by the libraries, CU Boulder libraries will retain a local heading as the "authoritative heading", and add the authoritative heading as the local heading.
