I am still working on a "collections ecosystem" project and am trying to find a way to look up the call number ranges for specific areas of art, such as German sculpture or Chinese painting. I've found this document online, which breaks down a little bit when you click on the subclasses: https://www.loc.gov/aba/cataloging/classification/lcco/lcco_n.pdf But it doesn't break down nearly as much as I need. Can anyone help me find a more complete breakdown for the Ns and TRs? thanks, Karen Bouchard Brown University -- Karen A.
