The Center for Latin American and Caribbean Studies is the locus of Brown University's regional initiatives which have a particular focus on Brazil, Haiti, the Dominican Republic and Cuba. As part of Brown's educational and scholarly commitment to these projects, both the Rockefeller Library and the John Hay Library are contributing materials to the Digital Library of the Caribbean (dLOC).
A number of the John Hay Library's collections include rare materials pertaining to the Caribbean area. The most notable of these are the George Earl Church Collection and the Anne S.K. Brown Military Collection. Colonel George Earl Church was an American civil engineer and an explorer who worked on projects in Latin America and the Caribbean Basin. He bequeathed to Brown, upon his death in 1912, a substantial collection of 3,500-volumes comprising significant works dating from the 16th through the 19th centuries on Latin American and Caribbean politics, history, geography and economy, many of them quite rare. The Anne S. K. Brown Military Collection is the foremost American collection of material devoted to the history and iconography of soldiers and soldiering, and constitutes one of the world's largest collections devoted to the study of military and naval uniforms. It was compiled over the course of more than five decades by the late Mrs. John Nicholas Brown (1906-1985), and is still growing. It contains approximately 12,000 printed books, 18,000 albums, sketchbooks, scrapbooks and portfolios, (containing thousands of prints and drawings), and over 13,000 individual prints, drawings and water-colors as well as a collection of 5,000 miniature lead soldiers. The Hay Library also has rare materials from the Caribbean in its Harris Collection of American Poetry and Plays, its History of Science Collection and its general collection of rare books, known as the Starred Books collection.
