LCSH to Local Headings Map

As we are going through our collections, we are introducing local and alternate subject headings to replace language that we feel is outdated. This table represents the changes made to date, and it will be updated as more changes are made. 

When adding a Local subject heading, we make the following changes to the authority record:

1. In 008, change Subject heading system/thesaurus value to "z" (this should indicate that instead of LOC or another system, this record is local).
2. Add new heading in 1XX with a 7 in second indicator and add subfield "$2local" (unless the new term is taken directly from another thesaurus or vocabulary - ie terms in Homosaurus instead have a "$2homoit").
3. Put original 1XX in 4XX with $w ane| (this is only done with the main entry authority record - not each record with various subfields).
4. Add note 667 with text "Main entry changed to a local heading in YEAR [optional - add old term and new term if helpful] by NAME according to JUSTIFICATION (INCLUDE URL IF APPLICABLE). Original term added as former heading." [If you need to customize here do so - sometimes only 4XX or 5XX's are changed, not main entry].

Please Note: While we used to display our local headings in a table directly in this post, we got too big for LibGuide! You can see a spreadsheet of all our local changes in the "Local Headings" box on our Critical Cataloging page.
