The Office of the Historian at the U.S. Department of State recently released over 100 documents from the published "Foreign Relations of the United States" (FRUS) series. The documents are specially designed to be read on a number of new devices, such as the iPad, and there are some real gems here. Visitors can use the Volumes and Browse by Administration drop down menus to get started. First-time users may do well to click through the 1952-54, Guatemala area. This rather prodigious volume "fills in many details about the role of the United States in Guatemala in the early 1950s." As those familiar with the topic may know, this involved the CIA as they attempted to implement U.S. foreign policy in the region. Each set of documents comes with a preface, information about abbreviations, and an introductory essay.
