The Perseus Project, at Tufts University (and one of the oldest digital libraries) devotes a section of the site to “Teaching with Perseus,” including syllabi and class notes, comment from instructor, and teacher and student guides. Similarly, the Colorado Digitization Project includes a section on “Working with Schools,” with lesson plans and links to additional tools and resources. Classes using these resources. Class using there resources could meet entirely in cyberspace, although it is likely that most of them do not. Digital libraries can, of course, support collaborative research activities among individuals who may be far removed from each other, and from digital library. This has been a subject of research interest- for example, the University of Michigan Digital Library site illustrates a visual collaborative information space in research on user interfaces- but little has surfaced in actual working demonstrations.
