no, i used only the official information from international isbn agency to produce this patch. Range Message (XML) from http://www.isbn-international.org/page/ranges we have much more information (payed) about publishers and its prefixes internally, but for hyphenation we dont need more information as provided in the above xml-file. additionally i put in support for the 979-prefix, because new ranges get applied to this new prefix. as far as i know old ranges will never change. regards, jan
