Readers will notice a further change in the appearance of the Quarterly Journal of Engineering Geology in this number. Following the change to a double-column layout last year, we are now using a lighter weight, less glossy paper, and have also reverted to stitched binding, rather than the side-stabbed, stapled binding that we have used for the past few years. Except for the last, these changes have been forced upon us by the inevitable need to economize, though it still remains the Editorial Sub-Committee's policy to maintain the high scientific and production standards that we have achieved in the past.
The economies that have been made in production costs have not entirely offset the effects of inflation. We have, however, been able to publish during the last year about 30% more material than was possible in 1977, and we anticipate a further, though modest, increase in the size of Volume 12 during 1979.
A major innovation is to acknowledge the contributions of the Society's flourishing Hydrogeological Group, and the increasing role of hydrogeology in the Journal's content. The Sub-Committee hopes that hydrogeologists will increasingly see the Journal as an international vehicle for their publications. There is no intention that hydrology should occupy journal space at the expense of engineering geology, but rather to allow the Journal to expand as demand dictates.
Along with these changes, readers will notice that the Society's journals are now being published by Blackwell Scientific Publications Ltd. We hope that with their help the continuing rise
