These presentations were noteworthy for me:
Meredith Farkas spoke about building collaboration, communication and community online. Her blog is Information Wants To Be Free.
Nicole Engard of Jenkins Law Library spoke about her library's use of intranet-based blogs and wikis for project management and documentation. Her blog is What I Learned Today. See her posting about "The Future of the Catalog" presentation with Tim Spaulding of LibraryThing and Roy Tennant.
David Lee King gave an excellent presentation on Guiding Libraries & Info Pros through Change.
