A clarification for MARC21: The $x is not valid in all 7XX fields. For those 7XX fields for which it is valid, it is an ISSN only (not an ISBN). ISSNs are waaaaaaaaaay more reliable than ISBNs, and are very, very, very useful for searching, so, yes, I think they should be visible in all the 7XX fields for which they are valid. (In the 754 field (Added Entry, Taxonomic Identification), $x is a non-public note. This is not a very commonly used field in most types of libraries, though.)
