In an earlier article - "Music Research in Spanish Libraries," published in Notes of the Music Library Association, sec. ser. X, i (December, 1952, pp. 49-57) - Richard Hill did kindly allow me to itemize my indebtednesses to the Spanish friends whose names make up two-thirds of the following list.
