Abstract : An attempt is made to lay the foundations for a theory of special classification designed to overcome the deficiencies of those theories based on Boolean Algebra. A partial system of propositional calculus is the model of this theory, the choice of primitive connectives being dictated by the conditions and requirements of retrieval. Specifically, the model is negationless and is so constructed to avoid the difficulties generated by the use of negation (complementation) in the theory of retrieval systems based on hierarchical classifications.
