This collection, which came to Logos via CP, consists of 27 works by 8 authors and includes sermons (in English and, in one case, also in Latin); dozens of letters; poetry; spiritual maxims; prayers; hymns; discourses; works of moral theology, mystical theology, and systematic theology; a devotional; three commentaries on parts of the Bible (one of which is breviary-centric); an autobiography; and a two volume catechism (only in Latin).
It's a great collection.
And parts of it appeal to many more people than might be inclined (or able) to buy the whole thing. After all, it contains a bunch of works aimed at different audiences and written in different genres by different authors in different languages. And since it's all public domain, Logos can break it up hassle-free.
PS: A similar argument can be made for breaking up the Medieval Preaching and Spirituality Collection with its 34 volumes by 21 authors and noticeably higher price. Please do. Many, even most, of your post-patristic pre-historical-critical method Catholic Bible commentaries are hidden in these two collections.
