I just thought it might be fun to know how to get formal recognition as existing, and into the Bodeleuan and British Library catalogues. If anyone's got any direct experience, that'd be handy. (And is there any equivalent for CDs and such?)
In the meantime, here is a contact page for Whitakers (one t) - nothing about ISBNs on it, but there wouldn't be.
And I found this on another site:
