First, I should verify Eduardo Diaz's connection to "Recuerdos". Maybe he wrote a guitar method or a book of songs. Let me check. Oh, I remember there's a famous guitar method called "Méthode pour la Guitare" by Fernando Sor, but maybe Eduardo Diaz is a different person. Wait, perhaps the user is referring to a specific PDF related to Eduardo Diaz's compositions or a method based on "Recuerdos".
