    Abstract
    The necessary and sufficient conditions for saying that X has a need for certain information are identified. It is concluded that an information need is a condition in which certain information contributes to the achievement of a genuine or legitimate information purpose. Information need is a relationship which obtains between information and information purpose; it is not a psychological state. Implications for research and practice are drawn from the conceptual analysis
