Abstract
This paper presents descriptions of four informa tion/system interface projects in progress at ESRIN, the estab lishment of the European Space Agency (ESA) in Italy. Each project demonstrates a somewhat different approach to mter face design, but all share the commonality of responding to user goals, tasks and charactenstics. It is suggested that next generation scientific information systems will have to be designed for direct access by end users to a large vanety of information sources, through a common interface. Design of such systems, including their interfaces, should be based on a multi-level analysis of user goals, tasks and domain views.
