The aim of this session is to review the nature of information and recent changes in information management systems, digital libraries and electronic publishing. The smallest such thing is an answer 'yes' or 'no' - something is or is not. Information theory and information science Information theory is concerned with the study of the integrity of the content of a signal as it is transported. It is not concerned with the semantic content of the signal.
Information science is concerned with the practice of storing and retrieving information.
It has become associated with the study of library management systems. They serve a cultural role in preserving and organising artifacts and ideas. Newsgroups, bulletin boards, listservers, etc. Electronic journals provide faster and cheaper publication of research results. In a traditional library, anything there has been bought and therefore someone has deemed it of sufficient quality.
