...and some types that the software controls automatically, but incorrectly. Specifically, form subdivisions which are also valid as topical subdivisions often incorrectly "flip" from x to z when controlling the heading. This seems to occur even when there is an explicit 180 validation record for the subdivision.

I trust OCLC is at least aware of this problem. The choice of x vs. v in a subject string is often the result of exacting intellectual work. And, in many systems, subfields x and v map to completely different indexes (or if they don't, they should). In light of the increasing emphasis of late on genre/form in library cataloging, I would hope this will be rectified at some point.

"Those who need structured and granular data and the precise retrieval that results from it to carry out research and scholarship may constitute an elite minority rather than most of the people of the world (sadly), but that talented and intelligent minority is an important one for the cultural and technological advancement of humanity. It is even possible that if we did a better job of providing access to such data, we might enable the enlargement of that minority."
