and for persons outside of psychology seeking informa-
tion about psychological matters, the Handbookvolumes
serve as a reference source for expanding their knowledge
and directing them to additional sources in the literature.
The preparation of this Handbookwas made possible by
the diligence and scholarly sophistication of the 25 volume
editors and co-editors who constituted the Editorial Board.
As Editor-in-Chief, I want to thank each of them for the plea-
sure of their collaboration in this project. I compliment them
for having recruited an outstanding cast of contributors to
their volumes and then working closely with these authors to
achieve chapters that will stand each in their own right as
valuable contributions to the literature. I would like finally to
express my appreciation to the editorial staff of John Wiley
and Sons for the opportunity to share in the development of
this project and its pursuit to fruition, most particularly to
Jennifer Simon, Senior Editor, and her two assistants, Mary
Porterfield and Isabel Pratt. Without Jennifer’s vision of the
Handbookand her keen judgment and unflagging support in
producing it, the occasion to write this preface would not
have arrived.IRVINGB. WEINER
