Journal of Librarianship and Information Science, Ahead of Print. Research on information need has a long-standing tradition. Within this body of research, certain lines of inquiry have been more predominant; for example, research on how information need is satisfied and the role of information need in everyday life. Undeniably, these lines of inquiry are of immense value; however, other avenues concerning information need deserve even more attention to ensure theoretical developments in the field of information behavior. These aspects include domain specification of the concept of information need, its operationalization and empirical validation. This study attempts to specify the conceptual domain of information need and articulates this domain through five aspects. These aspects shed light on the antecedents and consequents of information need, its descriptions, its role in life, and the relationship of information need with other needs. The proposed articulation should help in better theorization and operationalization of information need in empirical studies.
