This paper proposes an uncertainty principle for information seeking. The principle is based on the results of a series of studies conducted by the author into the user's perspective of the information search process. A basic principle of uncertainty is elaborated by six corollaries. The principle is proposed to explain the constructive process of information seeking and use bringing affective considerations to what has usually been regarded as a cognitive process.
