We've just completed the task of compiling something called "100 Essential Books for the Catholic Parish Library" (PDF file) here at Aquinas and More. It was quite a challenge to distill the great bounty of Catholic books down to just a core "100 Best" but we think we did a pretty good job. If your parish has a library or is interested in starting one, just download the list. Links are included for easy purchasing. We think it is a great starting point! Areas covered include Sacred Scripture, Theology, Church History, Liturgy, Sacraments, Apologetics, Spiritual Classics and Children's books.
If you have suggestions on changes to the list, please let us know!
