This book constitutes the refereed proceedings of the 16th International Workshop on Computer Science Logic, CSL 2002, held as the 11th Annual Conference of the EACSL in Edinburgh, Scotland, UK, in September 2002. The 37 revised full papers presented together with 3 invited papers were carefully reviewed and selected from 111 submissions. The papers are organized in topical sections on rewriting and constructive mathematics; fixpoints and recursion; linear and resource logics; semantics; temporal logics and games; probability, games, and fixpoints; complexity and proof complexity; ludics and linear logics, lambda-calculi; and resolution and proofs.
