“This paper considers the nature of information science as a discipline and profession. It is based on conceptual analysis of the information science literature, and consideration of philosophical perspectives, particularly those of Kuhn and Peirce. It is argued that information science may be understood as a field of study, with human recorded information as its concern, focusing on the components of the information chain, studied through the perspective of domain analysis, in specific or general contexts. A particular aspect of interest is those aspects of information organization, and of human information-related behaviour, which are invariant to changes in technology. Information science can also be seen as a science of evaluation of information, understood as semantic content with respect to qualitative growth of knowledge and change in knowledge structures in domains. This study contributes to the understanding of the unique ‘academic territory’ of information science, a discipline with an identity distinct from adjoining subjects.” (Lyn Robinson and Murat Karamuftuoglu ~ Information Research 15.4)
