This Encyclopedia is the first attempt in a generation to map the social and behavioral sciences on a grand scale. Not since the publication in 1968 of the International Encyclopedia of the Social Sciences, edited by David L. Sills, has there been such an ambitious project to describe the state of the art in all the fields encompassed within the social and behavioral sciences. Available in both print (26 volumes) and online editions, it comprises 4,000 articles, commissioned by 52 Section Editors, and includes 90,000 bibliographic references as well as comprehensive name and subject indexes.
