These projects deal with information capture, storage, retrieval, and display. The best place to keep abreast of them is through their Web sites. To read more about the projects or related research, see IEEE Computer, May 1996 ( computer/computer.htm), or D-Lib Magazine (). The first issue of the International Journal of Digital Libraries (Springer Verlag) will be launched next month.

(6) Stanford University Digital Libraries Project Principal investigators: Hector Garcia-Molina, Terry Winograd Summary: a series of five principal projects addressing aspects of interoperability over heterogeneous services and collections. They are built around the "InfoBus" protocol, which provides a uniform way to acess a variety of services and information sources through "proxies" acting as interpreters between the InfoBus protocol and the native protocol.
