Ben, this is one of the complex things about publishers. I don't believe
there is an error here. If you look at the ones with ISBNs, they use the
same publisher identifier:
1432539787
1432577166
(The "4325" is the publisher ID).
The same publisher (read: company) often publishes multiple imprints.
Thus "Vintage Books" is an imprint of Random House (or was, I can't
remember who still exists due to the many buyouts). OCLC did an entire
study of trying to see if they could identify the publishers from the
bib data and ISBNs:
Connaway, Lynn Silipigni, and Timothy J. Dickey. 2011. "Publisher Names
in Bibliographic Data: An Experimental Authority File and a Prototype
Application." Library Resources and Technical Services, 55,4. Pre-print
available online at:
http://www.oclc.org/research/publications/library/2011/connaway-lrts.pdf
(.pdf: 388.5K/41 pp.).
The method they used was very close to what Edward Betts did for the
Open Library.
I also often suspect that some small publishers join together to use an
ISBN ID because it's cheaper for them. But I don't have any proof of that.
