Since its inception in 1966, the series of numbered volumes known as Semiconductors and Semimetals has distinguished itself through the careful selection of well-known authors, editors, and contributors. The "Willardson and Beer" Series, as it is widely known, has succeeded in publishing numerous landmark volumes and chapters. Not only did many of these volumes make an impact at the time of their publication, but they continue to be well-cited years after their original release. Recently, Professor Eicke R. Weber of the University of California at Berkeley joined as a co-editor of the series. Professor Weber, a well-known expert in the field of semiconductor materials, will further contribute to continuing the series' tradition of publishing timely, highly relevant, and long-impacting volumes. Some of the recent volumes, such as Hydrogen in Semiconductors, Imperfections in III/V Materials, Epitaxial Microstructures, High-Speed Heterostructure Devices, Oxygen in Silicon, and others promise indeed that this tradition will be maintained and even expanded.Reflecting the truly interdisciplinary nature of the field that the series covers, the volumes in Semiconductors and Semimetals have been and will continue to be of great interest to physicists, chemists, materials scientists, and device engineers in modern industry.

Advances in Heat Transfer is designed to fill the information gap between regularly scheduled journals and university level textbooks by providing in-depth review articles over a broader scope than is allowable in either journals or texts.

Advances in Inorganic Chemistry presents timely and informative summaries of the current progress in a variety of subject areas within inorganic chemistry, ranging from bioinorganic to solid state. This acclaimed serial features reviews written by experts in the area and is an indispensable reference to advanced researchers. Each volume of Advances in Inorganic Chemistry contains an index, and each chapter is fully referenced.

That residues of pesticide and other contaminants in the total environment are of concern to everyone everywhere is attested by the reception accorded previous volumes of "Residue Reviews" and by the gratifying enthusiasm, Sincerity, and efforts shown by all the in dividuals from whom manuscripts have been solicited. Despite much propaganda to the contrary, there can never be any serious question that pest-control chemicals and food-additive chemicals are essential to adequate food production, manufacture, marketing, and storage, yet without continuing surveillance and intelligent control some of those that persist in our foodstuffs could at times conceivably endanger the public health. Ensuring safety-in-use of these many chemicals is a dynamic challenge, for established ones are continually being dis placed by newly developed ones more acceptable to food tech nologists, pharmacologists, toxicologists, and changing pest-control requirements in progressive food-producing economies. These matters are of genuine concern to increasing numbers of governmental agencies and legislative bodies around the world, for some of these chemicals have resulted in a few mishaps from improper use. Adequate safety-in-use evaluations of any of these chemicals per sisting into our foodstuffs are not simple matters, and they incorporate the considered judgments of many individuals highly trained in a variety of complex biolOgical, chemical, food technological, medical, pharmacological, and toxicological disciplines.

For more than thirty years, this serial has broadened the technical scope and expanded the scientific base of clinical chemistry. These volumes clarify the areas of molecular biology, informatics, and the monitoring of physiological parameters in critical situations as they pertain to clinical chemistry. Each volume of Advances in Clinical Chemistry contains an index, and each chapter includes references.

Humans are often distinguished from other animals by their ability, even need, to see patterns in everyday life. As we enter a new millennium, all aspects of society seem to want to take stock of what has happened in the past and what is likely to happen in the future.The computer industry is no different from others. Advances in Computers has been published continuously since 1960 and this year's volume is the fiftieth technical volume in the series (two index volumes were published as volumes 50 and 51). Since it is the fortieth year of publication, we decided to look back on the changes that have occurred since Volume 1 of Advances in computers appeared in 1960.We looked at the six chapters of that initial volume and decided that an appropriate anniversary volume for this series would be a collection of papers on the same topics that appeared in 1960. What has happened to those technologies? Are we making the progress we thought we would or are events moving more slowly? - Business computing - Numerical weather prediction - Spoken language - Language understanding - Microprocessor design - Computer games
