Preface An International Conference on Preconditioned Conjugate Gradient Methods was held at the Faculty of Mathematics and Informatics, University of Nijmegen, The Netherlands on June 19-21, 1989.

The main motivation in organizing this Conference was the wish to bring together specialists working on iterative solution methods, in particular using preconditioning methods. The conference was preceeded by a short course on preconditioned conjugate gradient methods, on June 15-17, 1989. Although the conference was organized and announced only a few months prior to its taking place, many scientists from different countries attended the conference. The director of the faculties of sciences, dr.ir. L.H.J. Wachters, had kindly accepted the invitation to open the conference. The topics presented at the conference contained both analysis and implementational aspects of the methods. The proceedings contains the full text of 11 invited or contributed papers. We are grateful to the participants, and especially to the speakers who made this meeting an important scientific event. We are also most indebted to the Administration of the Faculty of Mathematics and Informatics, to the younger members of the numerical analysis group and to the secretatiat of the Institute of Mathematics whose support was an indispensable contribution to the success of t
