A NISO/DCMI Webinar, http://www.niso.org/news/events/2012/dcmi/library_data/ will be held online at 13:00 Eastern Time on 22 February 2012. Library cataloging practice continues to have elements of the era of printed catalogs and alphabetized cards, and needs to modernize to take advantage of new information technologies. Karen Coyle will present her "five stars of library data," an analysis of the changes needed and some steps that libraries can begin to take immediately. She will also discuss the "open world" view of the linked data movement and how this view can increase the visibility of libraries in the global information space. Registration closes on 22 February 2012 at 12:00 Eastern Time.
