Preface
This volume contains the papers which have been accepted for presentation at the Third In-
ternational Symposium on Programming Language Implementation and Logic Programming
(PLILP '91) held in Passau, Germany, August 26-28, 1991. The Symposium was preceded
by two workshops which took place in Orldans, France, May 16-18, 1988 and in Link6plng,
Sweden, August 20-22, 1990 (their proceedings were published as LNCS volumes 348 and 456
respectively).
The aim of the Symposium was to explore new declarative concepts, methods and techniques
relevant for the implementation of all kinds of programming languages, whether algorithmic
or declarative ones. The intention was to gather researchers from the fields of algorithmic
programming languages as well as logic, functional and object-oriented programming.
In response to the call for papers, 96 papers were submitted. The Program Committee met
on April 30 and selected 32 papers, chosen on the basis of their scientific quality and relevance
to the Symposium. At the Symposium, two invited talks were given by Hassan Ai't-Kaci and
David B. MacQueen. Several software systems were presented, showing new developments in
the implementation of programming languages and logic programming.
This volume contains the two invited presentations, the selected papers and abstracts of the
system demonstrations.
On behalf of the Program Committee the Program Chairmen would like to thank all those who
submitted papers and the referees who helped to evaluate the papers.
The support of
ALP (Association of Logic Programming),
FORWISS (Bayer. Forschungszentrum flit Wissensbasierte Systeme),

is gratefully acknowledged. Andy Miick, Margit Berger, Heidrun Walker and several other mem-
bers of the department provided invaluable help throughout the preparation and organization
of the Symposium. We also would like to thank Springer-Verlag for their excellent cooperation
concerning the publication of this volume.
