The paper is a review article comparing a number of approaches to natural language syntax and semantics that have been developed using categorial frameworks.

It distinguishes two related but distinct varieties of categorial theory, one related to Natural Deduction systems and the axiomatic calculi of Lambek, and another which involves more specialized combinatory operations.
