> Thanks to Mac and Roy, we now have some hard numbers revealing the number of records having no association with ISBN numbers or are associated with multiple ISBN numbers. This is just one side of the problem. The other side, mentioned several times, is the association of a single ISBN number with two or more works or instances. It would be equally informative if the numbers could be generated to illustrate the size of this problem.
