Putting on my teacher/trainer headgear here: In the hand-press period (1450-approximately 1830), how a book is bound is
<i>always </i>copy-specific. That means a difference in how two copies are bound is irrelevant to how the book was issued (which is what you're cataloging), which in turn means that your two copies are of the same edition/issue and belong on the same record.
One copy is imperfect (lacking the portrait), and has significant copy-specific characteristics (interleaved and in two volumes). </div>

Something for you to investigate 🙂</div>

<p style="margin: 0cm; font-family: Aptos, sans-serif; font-size: 12pt;"><span style="font-family: Georgia, serif;">Dear Thumy, </span></p>
<p style="margin: 0cm; font-family: Aptos, sans-serif; font-size: 12pt;"><span style="font-family: Georgia, serif;"> </span></p>
<p style="margin: 0cm; font-family: Aptos, sans-serif; font-size: 12pt;"><span style="font-family: Georgia, serif;">We get a fair number of interleaved books. </span></p>
<p style="margin: 0cm; font-family: Aptos, sans-serif; font-size: 12pt;"><span style="font-family: Georgia, serif;">If the interleaved pages are blank or mostly blank, I would not make a second record for the interleaved version, since it was presumably interleaved
when it was bound rather than when it was published (unless you can find evidence to the contrary). I would use the same OCLC record for both items and add a local note indicating that copy # is missing the portrait, includes X number of blank or mostly blank
leaves, and is bound in two volumes.</span></p>
<p style="margin: 0cm; font-family: Aptos, sans-serif; font-size: 12pt;"><span style="font-family: Georgia, serif;">If the interleaved pages were heavily annotated, however, I might create a separate manuscript record for the interleavings with a 501 noting that
it is bound with copy # <i>Principia</i>. Then I would put both copies of the <i>
Principia</i> on the OCLC record, add a local note indicating that copy # is missing the portrait and bound with the manuscript in two volumes, and then link the item records for the manuscript and copy # of the
<i>Principia</i> in my ILS. If that makes sense?</span></p>
