The ACS Symposium Series was first published in 1974 to pro­
-vide a mechanism for publishing symposia quickly in book form. The
purpose of the series is to publish timely, comprehensive books de­
-veloped from AC S sponsored symposia based on current scientific
research. Occasion-ally, books are developed from symposia sponsored
by other organizations when the topic is of keen interest to the chem­
-istry audience.
