The Digital Library Federation lists twenty-two partner institutions, and coordinates initiatives across those partners. However even they do not have a listing of digital libraries. I2 management itself should maintain an active online I2 and related projects database which includes sociotechnical considerations.

Nora Sabelli, Senior Program Director for NSF, describes different outcomes that drive technology-enhanced learning research [13]: theory building, building the knowledge base, and establishing education practice. She calls for research on education practice to be systemic, research on education policy to be credible, and long term reform research to be achievable, fundable, and lead to demonstrable, sustainable

and scalable outcomes.

The domain of technology-enhanced learning research is vast. Each of the subsections in this paper could be a paper unto itself, identifying more specific key research issues in that domain. Some I2 projects are conducted by education scholars but most are developed by engineers and content experts. Education researchers might consult with emerging I2 projects to identify areas of potentially fruitful research and to provide education research expertise. Some projects already developed by engineers and content experts present opportunistic research test beds. Other I2 projects should be developed with education researchers as key participants from their inception.
