    Abstract
    Using Bertram Brookes fundamental equation, sets out a method for calculating the information content of an information process. The knowledge structure variables in the Brookes' equation are operationalized, following principles set out in Claude Shannon's mathematical theory of communication. The set of 'a priori' alternatives and the 'a priori' probabilities assigned to each member of the set by the person undergoing the information process is the operational definition of the variable K(S) from the fundamental equation, which represented the person's knowledge structure before the information process takes place. The set of the a posteriori alternatives and the revised probabilities assigned to each member of the set by the person undergoing the information process is the operational definition of the Brookes variable which is the person's knowledge structure after the information process take place. Gives an example of an information process from a recent archeological discovery
