Abstract

Epistemological theories of information science have a fundamental impact on theories about users, their cognition and information seeking behaviour, on subject analysis, and on classification. They also have a fundamental impact on information retrieval, on the understanding of 'information', on the view of documents and their role in communication, on information selection, on theories about the functions of information systems and on the role of information professionals. Asserts that information science must be based on epistemological knowledge, which avoids blind alleys and is not outdated. Shows limitations in the dominant approaches to information science and proposes alternative viewpoints
