Jay Weitz Senior Consulting Database Specialist OCLC Online Computer Library Center MC 139 6565 Kilgour Place Dublin, Ohio, USA 43017-3395 Phone: +1-614-764-6156 Fax: +1-614-718-7195 E-mail: [log in to unmask] ***** 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. -----Original Message----- From: Maps, Air Photo, GIS Forum - Map Librarianship [mailto:[log in to unmask]] On Behalf Of Angie Cope, American Geographical Society Library, UW Milwaukee Sent: Tuesday, September 06, 2011 10:01 AM To: [log in to unmask] Subject: Creating 655s for old records -------- Original Message -------- Subject: Creating 655s for old records Date: Sat, 3 Sep 2011 06:36:49 -0500 From: Christopher Winters <[log in to unmask]> To: [log in to unmask] <[log in to unmask]> 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 Christopher Winters Bibliographer for Geography, Anthropology, and Maps University of Chicago Library
