I understand your point of view. But I still disagree. What use do you
foresee for the catalogue numbers?

A more extreme problem: I have a box set (cat#=NTCD1952) that contains
two cds which are available separately (cat#=NTCD354 & NTCD385). Once
removed from the box, nothing distinguishes the cds from releases
bought separately. How would you enter it?
