BISAC Subject Headings Lookup or Crosswalk

From: Ryan Eby <ryaneby_at_nyob> Date: Wed, 21 Jan 2009 12:12:13 -0500 To: CODE4LIB_at_LISTSERV.ND.EDU

I was wondering if anyone knows of a good BISAC Subject Headings
source for looking up a recommended BISAC based on ISBN, LCSH, etc.
I've found some pages on oclc.org saying they were starting work on
crosswalks and possibly including them in WorldCat but I haven't seen
any returned in any WorldCat api calls yet. I've also read that ONIX
records often have a BISAC code, is there a good source that might
cover many publishers?
