Subject: "Bad" ISSN searches

Hallie and others--

Thanks to Steve and Robert for answering that the publisher is, indeed,
mis-printing the ISSN.  Some information about the ISSN and its
construction might help here.  The ISSN is made up of 7 digits plus what
is known as a check digit, which is helpful for detecting mis-transcribed
numbers.  The check digit is the result of a calculation on the previous 7
digits such that only one eighth digit is possible.  OCLC searches on only
the first 7 digits.  Therefore, the record retrieved for ISSN 0744-9626
is, in fact, the correct record for the 7 digit combination.  The fact
that the record retrieved does not match the title in hand indicates that
the publisher has mis-printed the ISSN since the correct last digit for
ISSN 0744-962 can only be a "3."

I hope this helps explain some OCLC searching results and how to interpret
NSDP records.  If you have further questions, please do contact me.
