This book is the first comprehensive treatment in English of the ideology and practice of the Inquisitional censors, focusing on the case of Mexico from the 1520s to the 1630s. Others have examined the effects of censorship, but Martin Nesvig employs a nontraditional approach that focuses on the inner logic of censorship in order to examine the collective mentality, ideological formation, and practical application of ideology of the censors themselves.

Nesvig shows that censorship was not only about the regulation of books but about censorship in the broader sense as a means to regulate Catholic dogma and the content of religious thought. In Mexico, decisions regarding censorship involved considerable debate and disagreement among censors, thereby challenging the idea of the Inquisition as a monolithic institution. Once adapted to cultural circumstances in Mexico, the Inquisition and the Index produced not a weapon of intellectual terror but a flexible apparatus of control.

"A unique and thorough study of Inquisitional censors in the Mexican context."--Rebecca Price, Catholic Library World - Catholic Library World
