I updated Business::ISBN::Data thanks to a patch from Daniel Jakubik. As I was verifying some info, I noticed that the ISBN Agency now supplies the data as RangeMessage.xml. I've not noticed that file before.
I've modified Business::ISBN::Data to read from that file and included that latest version in the distro. Additionally, you can tell the module to use a different version of that file by setting the ISBN_RANGE_MESSAGE environment variable. I know some people on this list use the module and would appreciate any feedback, especially if I missed some edge case. Thanks, -- brian d foy <brian.d....@gmail.com>
