OCLC Technical Bulletin 236 (available at
http://www.oclc.org/oclc/tb/tb236/index.htm) has some changes of interest
for map catalogers.  Highlights follow.  Thanks again to our Principal
Cataloger, Adam Schiff for alerting me.  Kathryn

Fixed fields:
Prme (Prime Meridian) has been deleted from MARC and is no longer valid.
OCLC has deleted it from maps workforms and from the 006 for maps.

Proj (Projection) has a number of new codes defined

Relf (Relief) value c has been redefined as gradient and bathymetric tints
and a new code m has been defined for rock drawings

SpFm (Special Format Characteristics) - on the Maps workform, codes m for
Braille, tactile and q for Large print are obsolete and should be used
anymore.  Instead, use fixed field Form codes f (Braille) and d (Large
print).

007 $b has been defined/redefined for all formats as Special material
designation and the value u in $b is defined as "Unspecified".  007 $b is
mandatory now if you are using an 007.  There are new subfield e and
subfield g codes defined in the 007 for maps (see the technical bulletin for
the list of these)
