    Abstract
    Part of a larger study which aims to: empirically investigate book-index usage, behaviours, and the extent to which specific print index features affect a user's search for information; and to examine these features in an electronic environment and to determine the optimum specifications for indexes in electronic texts by gathering evidence from a controlled user study. Provides an overview of the research project, focusing on a subset of the results from the study of hard-copy book indexes. Describes observable behaviours of a sample of users when consulting different variations of a hard copy book index. Suggests a preliminary model at 3 levels of abstraction repressing users' behaviours when using a book index

    Abstract
    Gives an overview of a research project which had aimed to: empirically investigate book-index usage behaviours and the extent to which specific print index features affect a user's search for information; and to examine these same features in an electronic environment. Aims to determine the optimum specifications for indexes in electronic texts by gathering evidence from a controlled user study. Presents a subset of results from index use in both print and electronic formats. Suggests a preliminay model representing users' behaviours when using an index and suggests implications for system design

    Abstract
    Reports on research following on from an investigation of pictorial image attributes typically described by participants in several types of tasks which showed that perceptually stimulated attributes were most typically noted. Tests a template for image description to be used by naive image searchers in recording their descriptions of images. Results indicate that users may need training or more guidance in order to correctly assign descriptors to higher level classes
