Beginning with volume 41 (1979), the University of Texas Press became the publisher of the Handbook of Latin American Stuides, the most comprehensive annual bibliography in the field. Compiled by the Hispanic Division of the Library of Congress and annotated by a corps of more than 130 specialists in various disciplines, the Handbook alternates from year to year between social sciences and humanities. The Handbook annotates works on Mexico, Central America, the Caribbean and the Guianas, Spanish South America, and Brazil, as well as materials covering Latin America as a whole. Most of the subsections are preceded by introductory essays that serve as biannual evaluations of the literature and research underway in specialized areas. The Handbook of Latin American Studies is the oldest continuing reference work in the field. Dolores Moyano Martin, of the Library of Congress Hispanic Division, has been the editor since 1977, and P. Sue Mundell has been assistant editor since 1994. The subject categories for Volume 55 are as follows: Anthropology (including Archaeology and Ethnology) Economics Electronic Resources for the Social Sciences Geography Government and Politics International Relations Sociology
