I've discussed this with Katherine and here's what we think we would do:

- Use "-OIDtype assigned" with import.pl. This uses dc.Identifier (you
could change this if necessary) metadata to form the HASH ID, so you can
be sure to get a fixed OID. In your case you would use something like
the ISBN number.

- Use your option a (ii) to get the periodical pages. This seems to be a
simple way of getting the information you want, with a fixed URL, and
without getting involved in classifiers or multiple collections. One
complication is that you need to make sure the issues are returned in
the correct order from the search -- you would use "boolean" searching
and add "-sortmeta <IssueNumberMetadata>" to import.pl to achieve this.

Hope this helps,

All the best,

Michael
