the discussions and conclusions that emerged from the workshop itself. The commissioned papers as revised by authors following the workshop are reprinted intact in Appendix A, so the body of this report does not summarize them systematically. However, authors of and topics in commissioned papers occasionally were the focus of discussion during the workshop and so appear in that context. Other sources of information include published literature that was made available by participants during the workshop, additional feedback and comments from workshop participants after the workshop, and the other references that are cited herein.
Participants in this workshop were charged with examining a broad spectrum of issues, and many perspectives were expected. To provide readers of this report with the breadth and richness of those perspectives and insights, first a detailed overview and synopsis is provided of major themes from presentations by plenary speakers, from discussions that followed plenary presentations and reports from break-out sessions, and from general discussions throughout the workshop. The workshop's major themes are then organized and synthesized into critical issues and questions concerning 1) Curricular, Pedagogical, and User Issues; 2) Logistic and Technology Issues; and 3) Economic and Legal Issues. Finally, conclusions from the workshop and recommendations from the Steering Committee based on all the information at hand are provided.
