Thank you for this, JP. I will be adding them to my wishlist - at some point! Oh, to find an entire set.....!!
Many of St. Alphonsus' works can be found on the internet. Google books is a good source - you can often get pdf files with the full text of the book. Unfortunately, St. Alphonsus Liguori's greatest work, his monumental Moral Theology, has never, to the best of my knowledge, been translated into English.
