1. Total number of books I've owned.
The answer to this question is truly frightening. The current accurate census is about 15,000 this does not include last week's bookstore runs. Or the nearly 200 children's books I have waiting for me to bring home. In my life, given the very high turnover rate of my library previously I would guestimate that I have owned very close to 25,000 books.
I should note that a goodone third or so of these are my wife's collection of contemporary Romances/romantic thrillers, etc. Catherine Coulter, Amanda Quick, Jude Devereaux, J.D. Robb, etc. etc.
2. Last book I bought.
A Jesuit study of the books of Luke and Acts, the name of which escapes me at the moment.
3. Last book I read.
4. Five books that mean a lot to me.
The Riverside Shakespeare
The two-fold gems of the English language--unsurpassed and perhaps unsurpassable. Sorry GBS.
Ulysses James Joyce--for two reasons--the professor who taught the course said one very provocative thing that sent me in search of the truth he knew (The Catholic Church), and Joyce himself convinced me absolutely of the truth of the Catholic Faith in the context of the novel. He didn't mean to, but he couldn't really help it--grace always prevails.
Wilfrid Stinissen's Nourished by the Word: Reading God's Word Contemplatively
Carter Dickson Night at the White Priory Not because it was the best of the Sir Henry Merrivale but because it is the only one I own in a first edition signed copy.
