This site mostly aims to make available Catholic books, or notes and reviews on Catholic books that are not available elsewhere. But naturally, some people come to this site looking for certain particular Catholic books that are not available on this site–recently, for example, someone came looking for children’s books and missals. To help with this, we’ve added a custom engine to search for free catholic books. We plan to add a second search that will include both free Catholic books and books that are only available for purchase.
