This is a static version of the visuals of a presentation I gave to the ALA Subject on linked open subject authority data. I described how linked data from the Library of Congress (http://id.loc.gov/) can be used to improve subject cataloging and browsing. I describe how the data is structured (including a brief overview of RDF and SKOS), and explain how I have used it to improve The Online Books Page (http://onlinebooks.library.upenn.edu/) and the Penn Libraries' catalog. I also show how I augmented and enhanced the authority data from LC, and discuss how widespread use of linked bibliographic and authority data may change how we build and use catalogs in the future.
This presentation is an expanded revision of a presentation made at the Digital Library Federation fall forum in November 2010.
