    Abstract
    To make their system quickly usable, designers often build interfaces that reflect well-known manual activities. Demonstrates how undergraduates use their mental models for print encyclopedias to develop minimal proficiency with various electronic encyclopedias. Lower performance levels in the electronic systems are due to additional cognitive load required to adapt and develop mental models for the new systems. For the fact retrieval questions used in these relativley small data bases, the hypertext encyclopedia required less cognitive load than the 2 traditional Boolean-based systems. Adaptive designs that provide multiple system images are encouraged to support more comprehensive user understanding and more varied tasks

    Abstract
    Presents a study that identifies and examines the roles that information-seeking expertise and domain expertise play in information seeking in full text, and user search systems. This forms part of an investigation to characterise information seeking and to determine how it is affected by interactive electronic access to primary information. Distinguishes between the approaches of search experts and domain experts. Makes recommendations for systems design

    Abstract
    Reports progress and future plans for a project to study the interactions of users with information retrieval interfaces. Tests are run with professional data base searchers and with end users who are members of a profession but have little or no searching experience. Interfaces tested include a command language search system used to search DIALOG bibliographic data bases, a non-procedural system that produces DIALOG commands, and several full text systems, including one using hypertext. The intent is to determine which kinds of users perform best with each type of interface. The project is being conducted jointly bay the University of Toronto and the University of Maryland
