Wikipedia uses the DC metadata format for non-book objects, rft.identifier is part of the DC metadata format; if you are describing a book, you want to use the book metadata format. Jonathan is correct, rft_id is a possible place to put an accession number for a book, but only if you can make a URI out of it. You might also consider rft_dat as long as you include rfr_id. Great to hear LibraryThing is looking at COinS!
