This fourth edition of Roderic Camp's highly respected Mexican Political Biographies is an updated comprehensive biographical directory of leading state and national politicians in Mexico, covering the years 1935–2009. The original edition, published in 1976, was the first and only comprehensive biographical work on contemporary political figures in any language and served as the prototype for the Mexican government's brief foray into its own official biographical directory. The Mexican Supreme Court has cited every biography of justices in the third edition as the basis of its biographies in the late 1980s.

With updates of the existing biographies and appendices, plus almost 1,000 additional biographies, this fourth edition now features close to 3,000 entries and serves as a unique resource list of the chronological occupants of all leading national political posts. The need for such information has become even more pronounced since Mexico's political transformation from a semi-authoritarian to a democratic model.

This latest edition allows readers access to information about Mexican politicians into the new century, and like its earlier versions, will be a valuable tool for government officials, journalists, historians, social scientists, the business community, and students.

Finally, it includes a detailed bibliographic essay that identifies and explains the significance of biographical sources and has been enhanced by numerous up-to-date Internet sources. An added convenience is an accompanying CD that allows readers to search the biographies and appendices, enhancing the longevity, usefulness, and uniqueness of this edition.

Roderic Ai Camp is McKenna Professor of the Pacific Rim at Claremont McKenna College.
