I would like to hear what people think of my observations about the
design of contrib/isn. In particular, I'd like Jan Otto to contribute
- he probably has more domain knowledge than I do. I haven't heard
from Jan about the proposed regression test.
In producing this patch, did you work off the listing of all the
628,000 assigned publisher codes that is only available in book form
at a cost of €558? How might I verify the correctness of the new
ISBN_range, preferably without spending €558? :-)
