I'm aware that JSTOR versions of journals have the same ISSN as their
print ed. counterparts.

What about PDF versions of journals?  Are PDF versions considered
close-enough reproductions of the print journals and therefore can use the
same ISSN as the print editions?

Thank you.  Apologies if this has been discussed before.  I know that
ejournals generally need a different ISSN.
