Elections in the Americas: A Data Handbook [PDF ebook] 
Volume 2 South America

This two-volume work continues the series of election data handbooks published by OUP. It presents a first-ever compendium of electoral data for all 35 countries in the Americas since the introduction of universal male suffrage. Following the overall structure of the series, an initial comparative introduction on elections and electoral systems is followed by chapters on each country. Written by knowledgeable and renowned scholars, the contributions examine the evolution of constitutional and electoral arrangements and provide systematic surveys of the up-to-date electoral provisions and electoral rules. These widely differing rules exert considerable influence on party systems and political processes. Exhaustive statistics on all national elections and referendums are given in each chapter. Together with the other books of this series, Elections in the Americas is a highly reliable resource for historical and cross-national comparisons of elections and electoral systems worldwide.
