Tlaltenango History Books

There are a number of books written by a local historian in Tlaltanango,
Zacatecas by the name of Bernardo Carlos Casas:

Tlaltenango : una ciudad amurallada (1986)

Semblanza historica de la parroquia de Tlaltenango : 1544-1991 (1991)

Historia de Colotlán (1991)

Has anyone ever seen or read these books? Does anyone know of any other
microhistories of the towns in the “three-fingers” region of Jalisco or
of Southern Zacatecas?
