Preface As editor of this journal and as secretary of the Molecular Graphics and Modelling Society (Deutschsprachige Sektion), I have pleasure in presenting this volume: It contains a wealth of material including all aspects of molecular modeling, ranging from method development and application to multimedia data presentation. With over 200 attendees the workshop attracted more people than ever before. As always, the meeting was devoted mainly to talks by graduate students and postdocs, so that the traditional workshop character was once again evident. Thanks are due to all those who have submitted contributions and the keynote speakers Manfred Sippl (University of Vienna), Hugo Kubinyi (BASF Ludwigshafen) and Gerd Volkers (ETH Zuerich). Special thanks go to Dr. Michael Krug (Merck, Darmstadt) who was in charge of the organization of the scientific program and to Prof. Juergen Brickmann and his group for trouble-free course of the technical part of the program that also offered the chance to get insight into the possibilities of real multimedia application in the field of molecular modeling. The abstracts collected here give a flavour of the meeting. We do hope that this collection of abstracts will encourage attendance of the 10th Molecular Modelling Workshop 1996 in Darmstadt. The Molecular Modelling Workshops are organized under the auspices of the Molecular Graphics and Modelling Society - Deutschsprachige Sektion. Tim Clark, Erlangen 6th July 1995
