The collection is organized in three series: a history and miscellany file; correspondence; and scrapbooks. The history and miscellany file contains documents pertaining to the Mexican Border Campaign and the history of the MBV, newsletters, newspaper clippings, photographs, and other related material.
Incoming and outgoing letters in the correspondence series are arranged in four files: the correspondence of the National Commander, the correspondence of the National Adjutant, correspondence dealing with the MBV's attempt to secure the passage of legislation, and general correspondence of the MBV. The first three files are arranged chronologically. General correspondence is arranged alphabetically by correspondent.
The scrapbooks in the collection consist of a personal scrapbook of officer Roy R. Fredrickson, and a scrapbook containing material pertaining to the MBV's 50th Anniversary celebration in 1966.
The strength of the collection is in the material relating to the efforts of the Mexican Border Veterans (1954-1971) to secure recognition from the United States Congress as a legitimate veterans' organization. There are many letters between the national officers and various congressmen, principally Gardner R. Withrow of Wisconsin (3rd District) and Olin Teague of Texas, as well as a series of letters from the governors of many states whose National Guard units were activated for border service.
Of special note is the correspondence of the National Commander's office (1954-1963); the correspondence of the National Adjutant's office (1955-1971); and a file of the MBV bulletin, The Buglar (1957-1973).
