Hello, Paige.

Thanks for the reply.  We haven't had this indexing available either.
Recently we had the opportunity with our catalog vender (Innovative
Interfaces) to add indexes at no additional cost.  I proposed this one.  I
was able to convey a sense of how the code works, and how it is applied
how it is worthy of a separate index.  However, I was entirely at sea to
answer how this index would function.

What confounds me are two aspects:
1 that it is primarily numeric, with frequently an alphanumeric component
2 that other primarily numeric indexes are based on serially assigned
numbers, such as OCLC accession numbers, LC record numbers, even ISN
numbers have a serial component to them.

It is more like a classification number, indeed, it is based on a
classification system.  I suppose that makes it, too, a classification
number.  Maybe I'm making it more difficult than it needs to be.  As it
turns out, it is not going to be added as an index at this time.  Thus, I
am trying to get more information about this for the possible future when
it could be added.

Again, thanks for your information.  A contact at OCLC is excellent!

Ken
