Thanks for this. I wonder if I could take this opportunity to ask
whether the situation regarding ISBN-recycling could be clarified,
perhaps by stating explicitly that 13-digit ISBNs can only ever 
denote a single work (ie. declare re-use to be an error per the new spec).

(This question has come up a few times in the context of RDF data merging 
of descriptions of ISBN-identified material. Implementors have been
unsure as to whether it is reasonable to merge descriptions when they
see they same URI, since it is said  that ISBNs have on frequent
occasion been re-assigned/re-cycles).

Thanks for any advice,

Dan
