Re: identify ISSN numbers in an mrc file

Thank you dear Stefano,

i am aware of this module, it works great.

But my problem is, what clever regex to use, in order to identify if a
subfield's content, is an ISSN number. Say our mrc has ISSN numbers thrown
in any tag you could imagine...

So my approach, would be, to search the whole mrc, but i do non know which
regex to use...
