This bibliography of works on the second Vargas administration, 1951-54, was compiled by two members of the staff of the Centro de Pesquisas e Documentação da História Contemporânea (CPDOC) to commemorate the centenary of the birth of Getúlio Vargas (April 19, 1883). Its purpose is to encourage research on the late Vargas years by alerting scholars to works that help explain that complex period of Brazilian history. More than 950 titles of articles, memoirs, monographs, official reports, oral history interviews, and theses and dissertations are included. They were gleaned from the holdings of fourteen libraries in Río de Janeiro, and in most instances the location of the work is indicated as an aid to research. The titles are listed somewhat arbitrarily under one or more of thirteen categories: general works (52); political parties and politics (122); labor (45); populism and nationalism (69); development (411); Petrobrás (120); nuclear energy (18); foreign policy (54); the military (33); the 1954 crisis (50); administrative policy (23); presidential speeches and messages (22); and biographies, memoirs, and oral history (76). The heavy emphasis on development, politics, and Petrobrás reflects the concerns of contemporaries and of scholars working on the period to date. The nature of the sources under each category is discussed in broad terms in the introduction, but the entries are not annotated individually. While the bibliography is by no means exhaustive, it contains much for established Brazilianists and should be an invaluable guide for students entering on their first research projects in Río de Janeiro.
