Organisational semiotics occupies an important niche in the research community of human communication and information systems. It opens up ways of understanding the functioning of information and information resources in organised behaviour. This text aims to bridge the gap between the technical and social aspects of information systems and information technology. The chapters in the book are divided into two major sections. The first section deals with Communication and pragmatics, and organisational systems, while section two concentrates on organisational systems, which may or may not include a computer system as a component. All the chapters in the volume have been submitted to a review process of discussants and peer reviews.
