Hi, Derek,

You were dead-on right in your interpreting 
>I believe (correct me if I'm wrong) that I want the 016.9733 to end up

Whether the gods of LC should ever have caused so much trouble in splitting
up the constituent parts of a call number, the numbers map as you suggested
from 852h (the classification number, i.e. the sequence of alphanumerics
for all items on a given subject/topic) and 852i, the completion of the
call number (the item number, i.e. the sequence of alphanumerics yielding a
unique address/identifier for that particular object).

Some libraries seem to ignore the formal definition of the 852h and enter
the WHOLE call number in that field (classification part and item specific
designator); this certainly makes things easier, although it is not
strictly speaking correct. You could make a similar pitch to use the 852c
that way, although again, not strictly speaking correct. 

Just a quick addendum re: Larry Stamm's response -- at least, I think it
was Larry's part infra, but I wasn't quite clear who was writing, so my
apologies to Larry if this is a misattribution -- viz. what is arbitrary in
the '852'.

Of course, all of the structure of tags and subfields is arbitrary (in the
sense of having no real reason for having been designated as they are), but
the mapping of the 852 is a little more defined now. Remember to check LC's
MARC documentation to see what fields and subfields within fields are
defined and how they are used. The concise MARC info online is kept
up-to-date and it does contain examples to help clarify proper usage. For
