This Third Edition is a further revision of the material to reflect the experience of the contributors and users with the previous editions. The book will be systematically brought up to date and new sections will be added.

The Green Book strives to improve the exchange of scientific information between different disciplines in the international pursuit of scientific research. In a rapidly expanding volume of scientific literature where each discipline has a tendency to retreat into its own jargon this book attempts to provide a compilation of widely used terms and symbols from many sources together with brief understandable definitions and explanations of best practice. Tables of important fundamental constants and conversion factors are included.

This is the definitive guide for scientists, science publishers and organizations working across a multitude of disciplines requiring internationally approved nomenclature in the area of Physical Chemistry.

The Revision of the Green Book: Quantities, Units and Symbols in Physical Chemistry consists of preparation of the third edition. The typing of the whole text into a standard computer-readable format (Revtex) is taking time. It is being carried out under the supervision of M. Quack and a meeting of I.1 is planned for January1999 in order to finalize the text and get it to the printers. The main changes with respect to the second edition (Mills et al. 1993), except for producing the book on a computer, involve extensions in the field of surface chemistry and the treatment of uncertainties of measurement.

A complete draft document was submitted to public review comments until 31 March 2006.
