Although the map genre terms were developed when tag 155 genre terms
were still created as part of LCSH, the OCLC quality control staff
waited until the new LCGFT coding was available before making widespread
changes. QC staff envision several phases of work with existing map
format records to be followed by periodic clean up of records
subsequently added to WorldCat. In the first phrase we are dealing with
obsolete LCSH form subdivisions as well as some that are to remain as is:
For type = e or f:
For LCSH subdivision ... $v Aerial views Add 655 7 Aerial views. $2 lcgft
Change LCSH subdivision ... $v Bathymetric maps to ... $v Maps Add 655
7 Bathymetric maps. $2 lcgft
Change ... $v Maps for the blind & ... $v Maps for the visually
handicapped & ... $v Maps for people with visual disabilities to ... $v
Maps Add 655 7 Cartographic materials for people with visual
disabilities. $2 lcgft
Change LCSH subdivision ... $v Maps, Comparative to ... $v Maps Add 655
7 Comparative maps. $2 lcgft
Change LCSH subdivision ... $v Children's maps & ... $v Maps for
children to ... $v Maps Add 655 7 Children's maps. $2 lcgft
Change LCSH subdivision ... $v Index maps to ... $v Maps Add 655 7
Index maps. $2 lcgft
Change LCSH subdivision ... $v Maps, Manuscript to ... $v Maps Add 655
7 Manuscript maps. $2 lcgft
Change LCSH subdivision ... $v Maps, Outline and base to ... $v Maps Add
655 7 Outline maps. $2 lcgft
Change LCSH subdivision ... $v Maps, Physical to ... $v Maps Add 655 7
Physical maps. $2 lcgft
Change LCSH subdivision ... $v Maps, Pictorial to ... $v Maps Add 655 7
Pictorial maps. $2 lcgft
For LCSH subdivision ... $v Relief models Add 655 7 Relief models. $2 lcgft
For LCSH subdivision ... $v Remote-sensing images Add 655 7
Remote-sensing images. $2 lcgft
For LCSH subdivision ... $v Remote-sensing maps Add 655 7
Remote-sensing maps. $2 lcgft
Change LCSH subdivision ... $v Maps, Tourist to ... $v Maps Add 655 7
Tourist maps. $2 lcgft
Change LCSH subdivision ... $v Maps, Topographic to ... $v Maps Add 655
7 Topographic maps. $2 lcgft
Additionally, inverted subdivisions, e.g., "$v Maps, Topographic," are
also converted when they are in direct order, e.g., "$v Topographic
maps." Forms with typographical errors and other variations, e.g.,
"Maps, Topographical" and "Topographical maps" are also being searched
and converted. The 655 is added unless the very same 655 is already
present.
In addition, existing 655s coded as LCSH are being converted to 655s
coded as LCGFT when the particular map genre term is found in the LCGFT
list, i.e., Aeronautical charts, Atlases, Bathymetric maps,
Bottle-charts, Cadastral maps, Cartographic materials for people with
visual disabilities, Celestial charts, Children's maps, Comparative
maps, Digital maps, Early maps, Fire insurance maps, Geological maps,
Globes, Gores (Maps), Index maps, Manuscript maps, Mappae mundi, Maps,
Meteorological charts, Military maps, Mine maps, Miniature maps,
Nautical charts, Outline maps, Physical maps, Pictorial maps, Portolan
charts, Quadrangle maps, Raster data, Relief models, Remote-sensing
maps, Road maps, Statistical maps, Stick charts, Strip maps, Thematic
maps, Topographic maps, Tourist maps, Vector data, Wall maps, World
maps, and Zoning maps.
The initial round is focused on the LCSH subdivisions, especially since
specific subdivisions are to be replaced by generic subdivisions with
the loss of form information without the addition of the corresponding
655. The initial round of changes involves 1.1 million candidate map
records and should be complete by the end of October.
We will then look to see what unconverted 655s coded as LCSH are left
and process those. One or more subsequent rounds will deal with
spotting LCSH patterns with topical headings and the subdivision maps,
e.g., if "650 0 Fire insurance $z <place> $v Maps" then add "655 7
Fire insurance maps. $2 lcgft", etc.

I'd be grateful to hear if any organization has put together a set of
straightforward instructions for adding lcgft headings (655s) to older
cartographic-materials records that it would be willing to share.
Weren't OCLC or LC at least thinking along these lines? I'm imagining
something like:
if format = e or f
and
if 650 > Geology
add 655 7 Geological maps $2 lcgft
if format = e or f
and
if 651 $v = Maps, Topographic.
change 651 $v to Maps.
and
add 655 7 Topographic maps. $2 lcgft
and so on. Perhaps I've overlooked something, but I'm pretty sure that a
few dozen such rules could deal with 99% of the records.
Law librarians are apparently doing something like this--although lcgft
headings in law look to be much harder to derive mechanically from
elements in older records than is the case for cartographic-materials
records.
Thanks for any hints.
Best,
Chris Winters
