I know the “professionals” who work on search, taxonomies, the semantic web and the like will all know about this resource, but many who are interested in topics like “folksonomies” could do worse than spend a bit of time reading some of the papers published in the CSDL’s online library of publications. If you are interested in these kinds of topics, be prepared to set aside many hours for what you find, (and also to turn on your ‘academic publications’ bullsh*t filter – god how I detest some of the conventions of academic writing, much as I understand why they exist). – SWL
