It comprises 74 papers produced in camera-ready copy, an extensive account of the discussion that followed each paper, a list of participants and, importantly, a panel discussion and a summary report by the organizing committee giving conclusions and recommendations. The papers discuss the philosophy, applications, performance, and validation of diffusive sampling. Diffusive sampling, because of its relative simplicity and cheapness, is becoming widely used. This report provides an excellent account of the state of the art, and draws attention to the importance of validation of the various devices and their operation. R.D.

More than ever before analytical laboratories are,producing large quantities of data. This is facilitated by the use of robotics, computing integrators and autosamplers that are capable of handling more samples in a given time than hitherto. The sample submissions and the data, which must be subsequently transformed into information, have to be managed if the value of that information is to be maximized. At a stage in a laboratory’s development when the quantity of data is becoming a potential problem, action must be initiated. A Laboratory Information Management System (LIMS) then becomes an option to consider. This book, which will be especially useful to the prospective user of such a system, is divided into five sections. The first two sections provide information on the capabilities of LIMS and the essential features of the computing involved. Further sections describe some of the choices and the considerations to be made in the implementation of such systems. Finally, as the subject is developing rapidly, the wider uses of the associated computing facilities are discussed. Being edited from the contributions of 26 authors, the common format of each chapter is a commendable achievement. The Index and an even better
