Fairthorne’s theory of notification is an elegant example of a theory in information science
“Fairthorne’s theory of notification clarifies the foundations of information science. He defined ‘notification’ as ‘mention and delivery of recorded messages to users’, listing as the main elements of library operations: (1) Source (e.g., authors), (2) Code (e.g., language of a book), (3) Message (the signal), (4) Channel (e.g., microfilms), (5) Destination (e.g., reader) and (6) Designation (subject description).

“ Variables The scope of our activities and studies lie inside Discourse but outside Signaling, i.e., outside the scope of Shannon’s Information Theory. The variables involved are, in general terms, Source, Destination, Designation, and Message, Channel, Code. In the present context a Code is a symbol system used to indicate choices made from a set of Messages, and represented by patterns of physical events (signals or inscriptions) consistent with the physical mode and conditions of communication, the Channel, in the given social and physical environment. |
