- 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

- Abstract
- The authors present a study of the real-life information needs of 59 McGill University undergraduates researching essay topics for either a history or psychology course, interviewed just after they had selected their essay topic. The interview's purpose was to transform the undergraduate's query from general topic terms, based an vague conceptions of their essay topic, to an information need-based query. To chart the transformation, the authors investigate N. J. Belkin, R. N. Oddy, and H. M. Brooks' Anomalous States of Knowledge (ASK) hypothesis (1982a, 1982b), which links the user's ASK to a relevant document set via a common code based an structural facets. In the present study an interoperable structural code based an eight essay styles is created, then notions of structural facets compatible with a highimpact essay structure are presented. The important findings of the study are: (a) the undergraduates' topic statements and terms derived from it do not constitute an effective information need statement because for most of the subjects in the study the topic terms conformed to a low-impact essay style; (b) essay style is an effective interoperable structural code for charting the evolution of the undergraduate's knowledge state from ASK to partial resolution of the ASK in an information need statement.
