Web 2.0 tools and services clearly have matured and are nearing ubiquity for most 21st-century computer users. They present technologies accompanied by an ever-increasing wave of information, leaving many of us overwhelmed. So, how can libraries add measurable value to what is consumed via the internet while enhancing lifelong learning and inspiring involvement in our new and fascinating “Age of Participation?” Mairn demonstrates interactively a variety of internet tools and services that can be incorporated anywhere online and/or in physical library spaces and highlights strategies to help provide more visibility to library resources. He discusses ways to help generate practical ideas for adding value, including creating useful Twitter backchannels to inspire participation before, during, and after a presentation; starting Google Waves to communicate and share ideas; having actual voice conversations with groups in social networks; sharing your desktop screen so that you can show off your library’s online tools over the internet; hosting live music concerts, gaming activities, and other library events; affixing QR (Quick Response) codes to book spines, ID badges, and doors to help guide mobile library users in your physical spaces to come visit your digital library space; and more.
