    Abstract
    As part of ongoing investigation of information seeking behaviour of end users in electronic environments, a comparison was made of those users having expertise in a topic area and those with expertise in online searching. Computer scientists and online search specialists conducted assigned searches in a HyperCard database on the topic of hypertext. Both groups of experts were able to conduct successful searches and outperformed a novice control group. Search specialists took slightly less time tahn the domain experts, modified queries by adding terms found in the text, and tended to focus on query formulation. Domain experts focused on the text and used their domain knowledge for further question answering

    Abstract
    Explores the hypothesis that using a zooming graphical interface minimizes user disorientation when reading documents in an electronic environment. 36 graduate students at the University of Maryland at College Park, USA, were randomly assigned to read a hypertext document in either Pad++, a zooming graphical interface, or Mosaic, a jump-based interface. Questionnaires, observation, and taped interviews were used to compare and evalutae the use of the 2 interfaces with regard to learning time, performance and user satisfaction. Findings suggest as workstations become more powerful, a hybrid interface that adds continuous zooming to the existing mechanisms of scroll, pan and jump will emerge
