Scholarship on the first Vargas presidency and the Brazilian experience of those years has reached a level of sophistication that justifies a critical bibliography like this. The 1,337 entries include contemporary publications, secondary works (books and articles), and memoirs. The subject and period divisions are clearly delineated and defined in the long introduction. Entries were found in the leading libraries of Rio and São Paulo, and most United States authors on the period are covered. Materials searched up to 1981 found their way into the list, yet studies of this period are coming out fast enough to require the specialist to do some additional bibliographic research. The principal shortcomings of the work are the use of twelve broad subject headings instead of a real subject index; the lack of cross-references among the sections; and the lack of at least brief annotations. The specialist in modern Brazilian history, and perhaps of Latin American political history as well, will wish to own a copy or at least have it in the library.
