Some twenty-five kilometers from Huancayo, Peru, nestled in the Jauja Valley, in unbelievable tranquillity, there exists a center of learning: the library of more than twenty thousand volumes in the Convent of Ocopa. This Franciscan monastery now opens the doors of its wealth of printed resources to scholars and researchers, both men and women, from far and near. During a visit of only two days, the author consulted with the librarian, Father Julián Heras, O.F.M., took photographs of the library, examined briefly certain volumes, and photographed title pages, colophons, engravings, and any particular items of interest in the more valuable works. What follows is an attempt to describe the printed resources for research in a library that has been called by Raúl Porras Barrenechea “una biblioteca de insigne sabiduría.”
