Until now most Monroe scholarship has been limited to the resources available at the Library of Congress, the NY Public Library, the Monroe Museum, and the College of William and Mary. These collections are only a portion of the widely scattered material that is available. With some 35,800 entries, representing 182 libraries and archives in the U.S. and Great Britain, this catalogue provides researchers with access to the wider corpus of Monroe papers, including letters written by and to Monroe, documents pertaining to his private affairs, important public documents, and official accounts of governmental bodies. Arranged in chronological order, entries contain the names of correspondents or author, the date and place of writing, a precis of contents, a list of names mentioned, physical description of the item, enclosures if relevant, repository, and reference to any published copies. A comprehensive index enables the researcher to find entries by subject. Designed as a bibliographic tool, the catalogue, by means of the document precis, also provides a comprehensive summary of all extant Monroe correspondence. Thus the catalogue provides not only a guide to the location of Monroe's papers but also a comprehensive documentary record of Monroe's life and career.
