Information workers center on seeking, gathering, and interpreting information in order to provide value-added information as a basis for making decisions and judgments critical to the function of an enterprise. This longitudinal case study investigates changes in perceptions of the information search process of an early career information worker as he becomes more experienced and proficient at his work. Building on Kuhlthau's earlier research, comparisons of the user's perceptions of uncertainty, complexity, construction, and sources in information tasks were made over a 5-year period. This is a case study, but it provides insight into issues raised in prior quantitative studies of securities analysts.
Carol Collier Kuhlthau (Fri,) studied this question.
