This report provides a brief general summary of progress in a 2-year project renewing earlier work on the development of Individualized Instruction for Data Access (IIDA)--a system for teaching online searching techniques for bibliographic data bases--as well as an in-depth report on the IIDA computer system design. The Connector for Networked…

A model is proposed for developing and implementing a community-based lifelong learning resources system. The model, which is based on systems theory, features the following sequence of activities: identifying all the learning resources in a community, incorporating information about these resources into a database, establishing a mechanism for…
