    Abstract
    Analyses the concepts species, class and set to explain the development of generic arrangement beginning with Aristotle's theory of essences. Explains the development from Aristotelian essences to the acceptance of accidental characteristics, culminating in the logical algebra of Boole and in a distinction between classes (as the extension of a concept) and sets (as a grouping of elements). Discusses 2 problems relating to indexing theory, selected from PRECIS and the work of Das Gupta
