This volume consists of 20 papers drawn from both academia and industry, first presented at the Fourth Compulog-Net Workshop on Parallelism and Implementation Technologies for (Constraint) Logic Languages held in Bonn in September 1996 and at the Fifth Workshop on Parallelism and Implementation Technology for (Constraint) Logic Programming Languages held in Port Jefferson in October 199. Papers on sequential logic programming systems focus on topics including constraint evaluation, support for extensions to logic programming, and abstract machines for performance evaluation. Papers on parallel logic programming systems also focus on a variety of topics including distributed implementations, garbage collection, and optimizations for exploiting and-or parallelism.
