Docs Dept. - and we use LC for classifying maps. Since LC is used for all the other collect ions in our library, it helps to maps less of a "neglected stepchild" and more accepted as a "real" library material. Jim Coombs Map Librarian Southwest Missouri State University Springfield, MO From [log in to unmask] Mon Aug 7 09:35:57 1995 Date: Wed, 02 Aug 95 14:46:23 CDT From: "Jennie Dienes, Univ. of Kansas" <[log in to unmask]> To: "Wendy S. Mann" <[log in to unmask]> Subject: Map Cataloging Question Dear Wendy: At KU, we use the T.R. Smith classification system to catalog our maps. This system has some base in the LC system where it comes to topos, especially topos of the U.S. For us, 3700s 24 is the classification number we use for United States USGS topos at scale 1:24,000. We arrange the maps (1) alphabetically by state, and (2) within each state, alphabetically by sheet. USGS topos at 1:63,360 get classed 3700s 63; 1:100,000 3700s 100; 1:250,000 3700s 250, etc. and arrange as noted in (1) and (2) above. At all these different scales, we keep all different editions together. So as an example, the sheets for Olathe, Kansas at 1:24,000 would be filed together whether they were the original edition, or photo-revised, or photo-inspected, or with minor revisions, or totally revised. We have not tried to keep them in any partic- ular sequence according to date or revision status. Since you are starting from scratch, the suggestions offered from other librarians to use LC are very compelling. Jennie. [log in to unmask]
