Acquired by Trinity University in 1982, the Ronald Hilton Collection was one of the largest private libraries on Latin America and the Caribbean. In addition to over 10,000 books (accessible via the library's catalog), the collection includes autographed letters from prominent Latin Americans, photographs of Cuba during the Spanish-American War, letters written to Hilton's shortwave radio program from listeners across the Western Hemisphere, and audiotapes of interviews with over 270 prominent figures in Latin American politics, academics, and culture.
