I believe the authority database for FAST headings is at http://fast.oclc.org/searchfast/  I'm not sure why they are not also in the regular authority file in OCLC.  More information about FAST headings is at http://www.oclc.org/research/activities/fast.html

At this point, our library wants to keep the headings, and we've (since I wrote my original mail to this list) asked Backstage to match them against their FAST database and deliver authority records for them. We aren't thrilled that these headings are displayed in the bib records in our catalog (Horizon's HIP), but we can't find a way to suppress their display (yet).

I review all authorities added every day in our catalog (just a glance over, usually) and these headings are creating more work for me, but I think in the long run, our decision to keep them is correct. Maybe in the future, our ILS could use them as intended.

I just discussed FAST headings with the catalog librarians of the HELIN Consortium yesterday. I've always maintained that we should only keep topical and genre headings in the catalog that are supported by authority records. When I searched OCLC last week, I didn't find any FAST authority records, though the 655 fields in the bibliographic records have authority record numbers in subfield 0:
