RE: marc field for ISBNs and ISSNs

["Abbott, Bruce" <BAbbot@xxxxxxxxxx>]

If you don't index it you can't search it.

Many vendors of electronic databases use the ISSN for the linking search
back to the catalog.  If that |z or |y ISSN is in the database record for
the title then the user will determine that your library does not have the
title in question if you don't index it.

I agree that it introduces problems and complexities into ISSN matching, but
for us at least, there is no choice but to index it.

Janet,

According to the MARC documentation those subfields are used when the number

is incorrect or invalid.  If the publisher has printed an incorrect number 
the item will show it even though some cataloging authority has determined 
that it is not correct.  MARC indicator info at:

http://www.loc.gov/marc/bibliographic/ecbdnumb.html#mrcb020
http://www.loc.gov/marc/bibliographic/ecbdnumb.html#mrcb022

Whether to carry this incorrect info in the bib record is usually answered
in 
the affirmative.  Whether to index by it is a trickier question.  What 
indexing on it will do to your match merge logic if you are doing subsequent

batch loads of record is an even dicier question...

I am finding records that have ISBNs or ISSNs only in |z or |y so this 
usefull information is being stripped out.  Do many of you out there load
and 
index "all" the subfields for the 02Xs?  I don't understand why some of the 
ISBNs are not in the |a since it is on the matching title I have in hand,
but 
when batch loading book and serial records to our OPAC it will increase my 
workload if I have to look at each title and edit that field.  TIA,  jk
