Hi Chris

First of all, don't be embarrassed about this question, it is one that
has
generated various discussions in map cataloging workshops.  As you can
see
from the emails at least two of our excellent map catalogers were using
the
GMD in difference ways.

The University of Florida has been cataloging maps on-line ever since
OCLC
loaded the LC MARC tapes.  I was lucky as the original NOTIS program for
maps was written in conjunction with our Heads of Cataloging and
Computer
Systems.  NOTIS could handle the maps in a separate partition and the
subfield h was not necessary.  Thus we were able the practice of Lib. of
Congress map catalogers, who did not use the h subfield map.  Over the
decades, on OCLC I have seen some records where the GMD was used. It has
been my experience that majority of these were from libraries that did
not
have large collections of maps.  It was a way for their staff and
patrons to
be aware that there was a map microfilm set or road map available.  I
always
remember an LC cataloger telling me there was no right or wrong to this
but
it depended where the item would be located, i.e. a microfilm set of
maps in
the Map Library would be cataloged as a map and the format described in
the
300 field.  A map microfilm set located in a microfilm collection could
be
cataloged as a microfilm set with a h subfield map.

Hope this helps a little.  Be happy the revised version of the
Anglo-American Classification and Cataloging Rules for Cartographic
Materials is supposed to be available in the Fall, 2003.  It has been
expanded to deal with a lot of issues which have been unclear or whose
format has developed since the first edition.

I have an embarrassingly elementary map cataloging question.

Most large map libraries (including, I believe, LC) do not use the
theoretically correct GMD "$h[cartographic material]" in map records.
When
one encounters a GMD in map records on OCLC, it's usually from a smaller
library or else in an older record (and it's "$h[map]"). I'd be very
grateful if someone could provide a succinct history of the use/non-use
of
the GMD in map records (or refer me to a good source of information on
this).

Also, I notice that, among those libraries that do use a GMD for
cartographic materials, some put a period before the GMD in records with
a
245 consisting entirely of an a subfield, some after. Surely there's a
"right" place for this period--can anyone tell me where it is?

Many thanks.
