We have just added Ioannes Benedictus Perazzo to the PRDL: http://www.rester.us/prdl/author_view.php?a_id=4977. Online I can only so far find vol. 1 of his Thomisticus Ecclesiastes, which has interesting essays on various words or topics having to do with moral theology. Vol. 1 begins with Abstinentia and ends with Hypocrisis. We have a hardcopy here at the Center for Thomistic Studies Enjoy!
