[DCRM-L] When to create a new record?

[Thumy Webb]

Hello,

I don't often catalog rare materials (sadly!) and am looking for some
advice.

I have two copies of Newton's *Principia *from 1726. One copy appears to be
the volume described in OCLC #2185758. The second copy also appears to be
the one described in that OCLC record *except* it was bound as two separate
volumes with blanks interleaved, and is missing the portrait.

Should I make a new bib record for the interleaved version? Do I use the
same OCLC record for both copies and explain the interleaving (is that a
word?) in a local note? Something else?

Thanks for any advice/opinions you can provide!
--Thumy
