Business::ISBN::Data(3) data pack for Business::ISBN


see Business::ISBN


You don't need to load this module yourself in most cases. "Business::ISBN" will load it when it loads.

These data are generated from the RangeMessage.xml file provided by the ISBN Agency. You can retrieve this yourself at <>. This file is included as part of the distribution and should be installed at ~lib/Business/ISBN/Data/RangeMessage.xml.

If you want to use a different RangeMessage.xml file, you can set the "ISBN_RANGE_MESSAGE" environment variable to the alternate location before you load "Business::ISBN". This way, you can use the latest (or even earlier) data without having to install something new or wait for an update to this module.

If the default RangeMessage.xml or your alternate one is not available, the module falls back to data included in However, that data is likely to be older data. If it does not find that file, it looks for RangeMessage.xml in the current directory.

The data are in %Business::ISBN::country_data (although the ``country'' part is historical). If you want to see where the data are from, check $Business::ISBN::country_data{_source}.
