The concept of information in Library Science, Sociology and Cognitive Science

The term information has become an essential concept in the field of library science and associated disciplines. The proper meaning of this term necessarily depends on epidemiological context. Moreover, its intra-theoretical and polysemic potential has led the term to be used in multiple senses, ranging from the context of cognitive psychology and, of course, to library science; however, the analysis offered herein underscores the need to define the term more precisely for use in library science and associated fields, so that its meaning is neither degraded nor over-simplified when building useful explicative models. This paper also shows that the meaning of this term has tendedto stabilize as required by theoretical models in which it is used, though as an isolated theoretical term it retains a degree of ambiguity.
