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 than welcome for this task on this page: https://www.wikidata.org/wiki/Wikidata:WikiProject_Freebase/Mapping
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?
