The welcome accorded other Annual Reviews has encouraged us to see if this Annual Review might render similar service in pharmacology. Where the world of pharmacology only a few years ago was largely academic and rather sparsely populated, it now extends to government and industry as well, and is getting settled, though not yet overcrowded. Publications have risen in accord with interest, and both outright pharmacological journals and pharmacological articles in other periodicals are greatly multiplied. Further, publications in pharmacology now go beyond the health professions. The impasse has clearly been reached, as in so many other fields of science, where one can no longer read all that one would like to, and finds reviews helpful. It is our intent that the reviews in the Annual Review of Pharmacology be critical and thus, we hope, helpful and that a summary of the progress of the current year or biennium be given in each general field of pharmacology.

By overlapping membership with the Editorial Board of Pharmacological Reviews, we hope to avoid duplication of topics, though in any event the purpose of broad annual reviews is different from that of reviews in depth of more limited fields.

We thank Professor J. Murray Luck for his general guidance and Miss Jeanine Ardourel, our editorial assistant, for her skill and devotion.
