It looks like publishers still get a "prefix" of their own (from the FAQ):
*What is the significance of the numbers in an ISBN?*
The five parts of an ISBN break down as follows:
1) The first three digits identify that it is an ISBN;
2) Identifies a *country* or group of countries;
3) Identifies a particular *publisher* within a geographic group;
4) Identifies a particular *title or edition* of a title;
5) A single digit at the end acts as a "*check digit*" to validate the ISBN.
It looks like we just have to ignore the 978 or 979 and treat the rest
like an ISBN-10 (since for this purpose we can also ignore the check digit).
