The author, who worked in the ANA for almost three years (1968-1969; 1973-1974), as well as in other archives germane to Paraguayan history, would like to extend his sincere gratitude to the Indiana State University Research Committee, the American Philosophical Society, the National Endowment for the Humanities and the Foreign Area Fellowship Program, for their very generous support. He would also like to dedicate this modest survey to Drs. Miguel Angel González Erico and Hipolito Sánchez Quell and other Paraguayan scholar-friends who have been so helpful over the years.

The Americas is happy to announce that this article is the first in a four part series of studies by John Hoyt Williams on Paraguayan Historical Resources. Part I, The Paraguayan National Archive; Part II, Other Paraguayan Archival Collections in South America, Europe and the United States; Part III, Newspaper, and Periodical Sources of Paraguayan History; Part IV, Selective Paraguayan Historiography. It is hoped to publish this series of articles later as a small pamphlet.]
