Included at the front of the series is a chronology of his career and life, written by his daughter (Ana Mujica) and daughter-in-law (Susana Rodríguez de Mujica Láinez). There is substantial correspondence from both Silvina and Victoria Ocampo; his close friend, and novelist Marta Lynch; his friend, and later, biographer, Oscar Hermes Villordo; as well as his Argentinian-Spanish friend Marcos Ricardo Barnatán, and his Spanish friends Guillermo Carnero and Luis Antonio de Villena.

The series is notable for the range of dates which the correspondence spans, 1927 to 1984, and for its varied documents which portray the Argentinian literary scene, primarily in the decades of the 1940s-1970s.
