    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
    The study of information needs has long be acknowlegded as one of the most important factors in the design of information services but has been hampered by the severe problem of designing user studies that will reliably measure them. Reviews the literature of previous research in this field, concluding that time and money are the chief constraints on information seeking behaviour. Describes a new observational technique for identifying the information needs of users and reports results of a small scale experiment to test the methodology. The observational technique involves the researcher being with the subject continuously throughout the day and observing their actions. The behaviour recorded was any action taken in order to answer a question. A small scale study was undertaken of 3 academics from the Psychology Department, University of Strathclyde, using the observational technique. The preferred technique of all the academics was to carry out their own research, followed by consultation with other individuals. One lecturer was a significantly heavier user of electronic media than the other two. The preferred physical locations of the information sources were personal collections and the University Library. One lecturer consistently used a wide range of sources while the other two strongly preferred to use personal contacts. Informal sources were found to be twice as popular as formal sources. A follow up questionnaire survey examined the possibility that previous training in the use of the library could explain the differences in the use of electronic information sources but results were found to be negative. Concludes that the new research tool developed for this type of study is both robust and likely to yield reliable information about user information needs

    Abstract
    Internet use research has focused on user surveys and novice learner studies, using survey, experimental, and ethnographic methods. They share a focus on user-based categories in the affective and cognitve domains. Information behaviour has an affective component that influences the direction of cognitive processing through hierarchically organized goals, characterized by both an individual and a cultural component. Research in human-computer interaction is evolving a user-centred methodology for system design and instruction that focuses on integrating affective and cognitive user variables to increase productivity, creativity, and human growth

    Abstract
    Reports on a survey of teenagers at a school in Edinburgh, Scotland, conducted as part of the Household Information System (HIS) project at Queen Margaret College. HIS has attempted to apply organizational models of information management to non organizational contexts such as households. Information management concepts have also been complemented by reference to research from sociology and media and cultural studies into the domestic consumption of technologies. Previous HIS research has suggested that notions of technological convergence proposed by producers and suppliers of Information and Communication Technologies (ICTs) are not shared by consumers who prefer to keep their television and computing devioces separate. Television is most often associated with relaxation and entertainment, computing with work and education. However, there is some evidence that expertise with regard to new ICTs is the province of children rather than adults in many homes, a trend which may indicate as inversion of traditional patterns of knowledge dispersal in adult child relationships
