2. Blessed Be God (a prayerbook that includes the Mass, a section on the Holy Rosary, chapters on contrition, avoiding sin, etc and some wonderful excerpts from the Angelic Doctor.
3. Franciscan Tertiaries' Manual (The Tertiaries' Companion) ca. 1914. Gorgeous art, all sorts of indulgenced prayers and it's Franciscan and it fits in a pants pocket with room to spare.
4. Leather-bound set of Butler's Lives of the Saints. Found it at a library in a pile of books that was being thrown away. They were practically like new, in their storage box, and are indispensable as teaching tools for my children, who had previously only had fictional Prot storybooks as a source for their 'heroes'.
5. I have to say a King James Bible for two reasons: One, I don't own a D-R yet, as anything not paperback is expensive and I would wear out a paperback in weeks, and two, while I don't have a D-R, even if I did, trying to share the Faith with an evangelical out of a Catholic Bible can be an impediment, esp if it's an impromptu discussion. My pocket-sized KJV is very handy. If I ever found a comparably-sized D-R, I'd buy 20 of them.
Immaculate Heart of Mary, triumph soon!
Most Sacred Heart of Jesus, have mercy on us.
