U. of North Carolina is especially rich with innovative takes on the commons concept. Latest is UNC - Asheville's
Collaborative Learning Commons:
"The Collaborative Learning Commons (CLC), currently being developed at UNC Asheville's Ramsey Library, brings together a variety of elements to foster student exploration and inquiry in new and creative ways. It is not a static computer lab. Rather, it incorporates the freedom of wireless communication, flexible workspace clusters that promote interaction and collaboration, and comfortable furnishings, art, and design to make users feel relaxed, encourage creativity, and support peer-learning. To this, add some specialized software, audio-video capabilities, self-help graphics services, color imaging, and production/presentation software catered to student learning and needs and it becomes a one-stop collaboratory for out-of-class assignments, writing, research, and group projects."
