Vile previously wrote The Constitutional Convention of 1787: A Comprehensive Encyclopedia of America's Founding (2005). He uses the biographical sketches in that encyclopedia as the basis for essays in this new work about the 55 men who served as delegates to the Constitutional Convention–whether or not they signed the document on September 17, 1787. Vile adds biographical information and detailed descriptions of each delegate's documented actions and opinions on the issues debated in the convention. He emphasizes delegates' views on the role and powers of Congress, the presidency, and the judiciary, and also federalism, a standing army, compromise plans related to federal-state powers, slavery, and individual rights. The alphabetically arranged essays include 'further reading' suggestions. Among his sources, Vile relies heavily on Max Farrand's edited The Records of the Federal Convention of 1787, a key compilation of documents, notes, and proceedings of the convention written by James Madison. He does not provide much interpretation or evaluation concerning delegates' influence, but instead offers a unique, descriptive guide to their convention participation and sources for further study. A glossary, quiz, and the text of the Constitution conclude the work. Summing Up: Recommended. Lower-division undergraduates through researchers/faculty; general readers.
