Andy,
The /book/book_edition/ISBN is a mix of -13 and -10 sometimes even weirder
:)
It was deprecated (but still holds value) about 3 years ago by Jeff Prucher
@ Google and we moved the -13 instances into
https://www.freebase.com/media_common/cataloged_instance/isbn13
Although I do not now if the copy (done by a bot script at the time by
Metaweb) was complete. It seems to be however by quick glance... there are
1.6 Million Cataloged instances alone from various OPACs, etc. that were
imported into Freebase in 2012.
I should probably jump into this and help you guys with this mapping.

As you may already know, I am currently working
on the importation of
Freebase content into Wikidata [1] using the primary source tool [2].
One of the big challenges of the migration is to build a good mapping of
the
properties of Freebase to Wikidata ones.There are
a few thousand of
properties so it is a task too big to be done alone. Your help is far
more
https://www.freebase.com/book/book_edition/ISBN could be P212
(ISBN-13) or P957 (ISBN-10). How would you like us to map that?
