A great presentation by Tim Spalding called What is Social Cataloging?, from the LIANZA 2009 conference in New Zealand. I recommend it if you’re at all interested in metadata, LibraryThing, or, I suppose, Tim Spalding.
Concluding Keynote at LIANZA 09 in Christchurch, NZ. Covers LibraryThing, tagging, personal cataloging, sharing, social networking, implicit and explicit social cataloging, collaboration, what’s wrong with OCLC and other exciting topics.
