The $0 is the correct field, but you would not link to this value: http://id.loc.gov/authorities/subjects/sh85095334 not the HTML page. The $0 and $1 are reserved for machine readable endpoints. They should *not* include links to HTML pages.

See: http://www.loc.gov/marc/bibliographic/ecbdcntf.html All that said, best check with a cataloger.
