Subject Navigation

Mapping the library future is a presentation done by John Mark Ockerbloom from the University of Pennsylvannia Libraries for the ALA Catalog Form and Function Group (Jan 12, 2008). It examines "Subject navigation for today’s and tomorrow’s library catalogs". He points out the richness of Library of Congress subject headings and the value of using subject maps to enhance browsing. Also comments on facets and use of tagging in library catalogs. It's about navigating library collections but the principles apply for any body of information.
