Thanks Ben! I tried ?rev=1, but didn't it didn't occur to me that the history mode would work.
On closer inspection, I actually did find this information in the dump in the source_records field e.g. "source_records": [ "marc:marc_records_scriblio_net/part28.dat:62741961:1376", "marc:marc_loc_updates/v36.i33.records.utf8:3020091:1375" ] for http://openlibrary.org/books/OL100043M.json I think that will provide enough information to do a tally. The first source record matches the source listed in the initial import. I'm not sure what the second source record is since I don't see it referenced in the change history http://openlibrary.org/books/OL100043M.json?m=history Thanks for setting me on the right path!
