Thomas Whigham and Jerry Cooney have provided a service to the profession by preparing a guide for Paraguayan sources in the United States. The collections are listed by state; materials including demographic data, diplomatic files, family correspondence, government papers, and missionary records are found in 27 states and the District of Colombia. Subject and collection indexes refer to the holdings by number. An introduction places the collections in perspective and emphasizes the significance of the colonial holdings at the University of Texas at Austin, the demographic data of the Genealogical Society of Utah in Salt Lake City, the twentieth-century materials at the University of California at Riverside and the University of Kansas, the Mennonite missionary materials, and the records of the U.S. government.

One wishes that the authors had located more private correspondence and described some collections more fully. Writing descriptions of collections with no guides is difficult, but the authors should have been more consistent as to the dates the collections encompass and the amounts of material on Paraguay they contain. At times it is difficult to know whether a collection merits a special trip or only a detour. Although many collections are well defined, such as the Society of Jesus Papers held by the University of California at Berkeley or the holdings of the University of Kansas, others are unclear as to the dates or amount of material on Paraguay; for example, the collection of the Council for International Exchange of Scholars Records held by the University of Arkansas. A similar problem arises in the description of the National Agricultural Library collection in Beltsville, Maryland. If one is doing research on Paraguayan social history between 1810 and 1864, should one travel to the Harvard University pamphlet collection? The book includes a long description of the Columbus Memorial Library of the Organization of American States, but no mention that this is primarily a twentieth-century collection. The Virginia Historical Society holds the Minor Family Papers, but how much is there on nineteenth-century Paraguay?

Finally, given the difficulty of locating newspapers, it would have been extremely useful if the text had provided information on Paraguayan newspapers. The authors note that the Missouri Historical Society possesses rare October and November 1858 issues of the Daily Morning Herald, a Saint Louis newspaper, and mention that the Manoel de Oliveira Lima Collection of the Catholic University of America holds Brazilian newspapers.

Researchers with interest in other parts of Latin America will find this guide useful because the collections described often have material for other regions. But those interested in Paraguay will find this guide a necessity. It is certain that the availability of this guide will accomplish the purpose that Whigham and Cooney sought: to facilitate research on Paraguay.
