Colección de documentos inéditos, relativos al descubrimiento, conquista y organización de las antiguas posesiones españolas de América y Oceanía sacados de los archivos del reino, y muy especialmente del de Indias : competentemente autorizada.

The collection was for the greater part published without any preconceived plan as to arranging the documents either systematically or chronologically. With v. 36 a chronological arrangement was begun, but was not consistently carried out. The extreme dates of the period covered by the documents in v. 34-42 are 1251-1796. cf. "Prólogo" to v. 1 of the 2nd series.
