One of the sessions I would have liked to get to at Umbrella a week or so ago (but I was getting to grips with my poster) was organised CoFHE/UCR and featured Lisa Hincliffe (University of Illinois at Urbana-Champaign) and Lisa Sloniowski (York University, Toronto). They talked about Digital Outreach and Social Engagement: connecting with users. They have a Library Outreach Wiki at http://libraryoutreach.pbwiki.com/ which I think they mentioned. If the sidebar isn't already displayed click sidebar on the right of the home page to see the list of active pages in the wiki: these are Enagement Techniques, Face to Face, Workshop Hints, Digital Outreach and Bibliography.
