This book constitutes the strictly refereed post-workshop proceedings of the 10th International Workshop on Computer Science Logic, CSL'96, held as the 5th Annual Conference of the European Association of Computer Science Logic (EACSL), in Utrecht, The Netherlands, in September 1996.
The volume presents 26 revised full papers selected from a total of initially 75 papers submitted; also included are two refereed invited contributions. The volume addresses all current issues in the area of computer science logic research, and is thus a unique record of recent progress in the area.

The lambda calculus was developed in the 1930s by Alonzo Church. The calculus turned out to be an interesting model of computation and became theprototype for untyped functional programming languages. Operational and denotational semantics for the calculus served as examples for otherprogramming languages. In typed lambda calculi, lambda terms are classified according to their applicative behavior. In the 1960s it was discovered that the types of typed lambda calculi are in fact appearances of logical propositions. Thus there are two possible views of typed lambda calculi: - as models of computation, where terms are viewed as programs in a typed programming language; - as logical theories, where the types are viewed as propositions and the terms as proofs. The practical spin-off from these studies are: - functional programming languages which are mathematically more succinct than imperative programs; - systems for automated proof checking based on lambda caluli. This volume is the proceedings of TLCA '93, the first international conference on Typed Lambda Calculi and Applications, organized by the Department of Philosophy of Utrecht University. It includes29 papers selected from 51 submissions.
