Book: Extractos de Informes Matrimoniales en el Obispado de Michoacán...

Guillermo Padilla Origel's book, Extractos de Informes Matrimoniales en el Obispado de Michoacán durante el Siglo XVII (1630-1685), is referenced a couple of times on NR and Somos Primos. Does anyone know if there is much overlap between what is available on Valladolid Dispensas and the extracts contained in the book? It does not appear to be available for purchase any longer.
