Half a century ago, this book would have been called perhaps ""Materials Toward a History of the Catholic Reformation."" It is not a narrative history of the Catholic (or Counter-) Reformation, but a collection of some fifteen of the most important and most illuminating documents from the first part of the era (1495 to 1540; i.e., Savanarola to Loyola). Each document is preceded by a short discussion of context and significance, and accompanied by ample bibliographical information. This volume -- and the second and final one, which is currently in preparation -- is, of course, intended for serious students either of history as such or of ecclesiastical reform. It is a well conceived and well executed work, sufficiently closely knit to serve as a documentary history as well as a source book. The scholar or student who does not have access to such forbidding and polyglot collections as the Corpus Catholicorum and the Reformationsgeschichtliche studien will be delighted with it.
