This paper provides a history and overview of the field of human information behavior, including recent advances and multidisciplinary perspectives. It defines key terms such as information behavior, information seeking behavior, information searching behavior, and information use behavior. The paper highlights the shift from a system-centered approach to a person-centered approach in understanding information behavior. It discusses the origins of research on human information seeking behavior, tracing it back to studies on library users and readership. The paper also explores the role of various disciplines, including psychology, marketing, and health communication, in understanding information behavior. It reviews studies on information needs and behavior, including the work of Mote, Ellis, Dervin, Kuhlthau, and Wilson. The paper emphasizes the importance of understanding the context of information needs and the barriers that impede information seeking. It also discusses new models and approaches in the field, including Wilson's problem-solving model and the integration of different models. The paper concludes that the study of human information behavior is now a well-defined area of research within information science, with new models and approaches emerging.This paper provides a history and overview of the field of human information behavior, including recent advances and multidisciplinary perspectives.
