    Abstract
    Library professionals in the informatio age are called upon to provide user firendly information environments. To accomplish this, more detailed knowledge is needed about the information behaviour of users. The concept of 'information counselling' reflects this new orientation and involves instruction activities such as: orienting, advising, and reassuring novice learners. The taxonomic approach tranforms self witnessing reports into classified segments of information behaviours at 3 levels of internalization and in 3 behavioural domains, including: affective, cognitive, and sensorimotor behaviour. Reference librarians and instructors are invited to contribute to the taxonomy and make use of it in planning an designing programmes and facilities

    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 results of a study, conducted at Hawaii University, Department of Information and Computer Science, to understand the novide searchers' experience in learning to use a WWW search engine. Without prior searching instruction, undergraduate novives wrote structured self reports during their first session on a Web search engine. Users choose their own topics and followed written instructions that prompted them to describe thoughts and feelings during specified stages of the search; pre search formulation; search statement formulation; search strategy; and evaluation of the results. The sentences in the self reports were numbered and then coded according to their affective or cognitive function. The affective sentences reveal how users set goals and limit the scope of the cognitive operations. Search acts appear to be governed by an affective filter that organizes incoming information and provides criteria for ranking cognitive relevance to search goal. Content analysis identifies reasons users have for rating self confidence, stress level, satisfaction, usefulness, and success with future searches
