Frequency is a good example of the mess that we have today in
AACR-type cataloging. There is a way to code frequency as a calculable
value in the MARC holdings record. That should suffice and there
should be no need for a note field if the value is provided. But notes
are "notes" because they are uncontrolled strings created by the
cataloger. Where other data in the record are either transcribed
strings or controlled headings, notes are neither. But the notes ARE
required by the cataloging rules.

This is evidence, to me, of the gap between the cataloging rules and
the actual practice of creating machine-readable catalog records. AACR
does not recognize that coded data (e.g. MARC fixed fields) exists.
Many notes repeat information that could be encoded elsewhere, but
because the note is what is required by the cataloging rules and also
displays in the catalog, the tendency has been to provide the note but
often not to provide the actionable data element. Obviously, it would
be a mistake to carry forward this practice, and instead the
actionable data element must be the primary source of data, from which
user-friendly notes can be derived if needed. That "if needed" part is
also something we should think about, because in fact in many system
displays notes are not included, so catalog users rarely see them.
Because notes have been favored over actionable data, there is a whole
host of information that is 1) not usable for any automated functions
and 2) rarely seen by users. Surely this is a waste of cataloger time,
and a disservice to our users.
