----------------------------Original message---------------------------- Betsy -- Thanks for sending proposed LC changes in cataloging carto. mtls. For the most part, they look either reasonable (given budget probs. we all face) or big improvements on what we now do (remote sensing headings). Just have these comments (since I won't be going to ALA): 1. 3.3D. Statement of coordinates & equinox I think it's not very forward looking to fail to apply this option when it's easily available on the piece being cataloged. Sooner or later there will be coordinate searching (it's now available in some systems like ImageQuery and it just seems inevitable that it will be widely available in the not-too- distant future in others). The future potential seems to be too great to jeopardize by failing to relatively economically add the data at the point of cataloging. It will be much more expensive, and perhaps prohibitively so do add this data retrospectively. Personally, I'm not at all concerned about adding data for celestial maps. There are compromises that could be made to economize if some other practices/rules were changed: a. Record info only in 034 and don't bother to repeat in 255 fields. b. If area covered is a standard political division or a city, e.g., a U.S. state or county, don't record. Put something into record to identify it so that at some future time the data could be automatically plugged in (if necessary) from a standard database of coordinates. Perhaps this type of coordinate info could somehow be linked to an authority file. The authority file would contain the coordinate info for standardized areas and be searchable and then linked through subject headings (or subject heading number) to bibliographic records. If LC drops putting in coordinate info when it's easily available I hope the records will be identified in the MARC record as less-than-full level. 2. Subject treatment for remote-sensing imagery. a. Punctuation conflict? "Remote-sensing images" but "Remote sensing" (without hyphen). b. Would be helpful to users and library staff to have links between "Remote-sensing images," "Image maps," and "Aerial photographs" as well as between "Remote sensing" and "Aerial photography." I don't care whether it's in a note or in a "see also" field. c. I assume that "Photographs from space," and "Photo maps" will be among the 450s under the replacement headings. cc MAPS-L Phil (Earth Sciences Library, Univ. of California, Berkeley; [log in to unmask])
