Lucky 13
This, taken from an Access Copyright email:
To allow for the creation of new numbers, the ISBN standard will be changing from a 10 to a 13-digit number effective January 1, 2007. Books published after January 1, 2007 will only be issued with 13-digit ISBNs (please note that ISSNs are not affected). It is expected that the book industry will begin conducting business transactions with 13-digit ISBNs only, however to support pre-2007 publications, 10-digit ISBNs are convertible to 13-digit ISBNs.
There’s a good explanatory piece about ISBNs, by the way, on Wikipedia. Seems they were invented by W.H.Smith booksellers . . . [more]
