Tom,

To begin with, let me explain the situations in which a publication
carries both an ISSN and an ISBN.  This most often occurs with annuals or
other types of directories, with serial travel guides, and with volumes in
monographic series.  In the case of annual or directory publications, the
ISBN identifies the particular year, e.g., 1998, while the ISSN identifies
the ongoing publication--the serial.  For monographs in a series, the ISBN
identifies the particular monograph and the ISSN identifies the ongoing
series.  For example, the series _Cookbooks of the World_ would be
assigned an ISSN, the volume, The Cooking of Italy would be assigned an
ISBN, but would also carry the ISSN of the series.

In trying to determine which record to attach your holdings to, you would
need to consider whether your library was collecting all the volumes of
the annual or just occasional years, or all the volumes in the series or
just occasional ones.  I will let others speak for the particular
practices in their libraries with regard to attaching holdings to records
since Library of Congress practices might not be typical.
