I was thinking that it might be nice to have a compilation of books to form a basis for an apologetic resource library. Commentaries, compilations of ECFs, church documents, and sound theological books are the sorts of things I have in mind. Like:

Catechism of the Catholic Church (obviously)
Theology for Beginners/Theology and Sanity by Frank Sheed

Dave Armstrong's A Biblical Defense of Catholicism is a must.

A Handbook of Christian Apologetics, Kreeft and Tacelli. It won't help a whole lot with doing apologetics with committed Protestants, but it'll help a ton with your half-catechized more-or-less sort of Christian of any sort.

I've heard the authors Ott and Jones referred to as well. What are the titles of their books?

Catholicism and Fundamentalism by Karl Keating

Catholic Verses by Dave Armstrong

Any Friend of God's Is A Friend Of Mine by Pat Madrid

Radio Replies (3 Volume Set) by Rumble and Carty

I've read each of these multiple times, they're so good and full of info.

Ott = Fundamentals of Catholic Dogma. It's a little out of date (pre-V II), and some quarrel with some of the translations, but it's still an invaluable reference.

Jones?

I like the Beginning Apologetics Series. Especially love the cheat sheet.

Weird, I was JUST going to post a similar request!

Jesus, Peter and the Keys by Butler, Dahlgren, and Hess.

But if I had to reccommend just one book, it would be Theology and Sanity, but you already know how brilliant it is.

Any book written by Scott Hahn

Dave Armstrongs website is the best single source of apologetic information on the web. You could spend months & months just reasing through the material...

The Christian Faith: In the Doctrinal Documents of the Catholic Church, ed. by Jacques Dupuis.

Lets not forget our most generous host Mr. Ray - He does have very good material.

The Bible, of course - perhaps the Haydock Bible.
CCC you've got but don't forget the Companion to the Catechism

Jurgens

Warren Carroll's History of Christendom

Sheed's Map of Life and To Know Christ Jesus

O'Connor's The Hidden Mana

Madrid's Search and Rescue (good source for recommended reading)

Aikin's The Salvation Controversy

Salvation is from the Jews

Mounce's Greek for the Rest of Us

Chesterton - Orthodoxy and The Everlasting Man

But that's just off the top of my head.

For all your early church fathers needs - Jurgens' Faith of the Early Fathers Vols 1-3

Oh my goodness yes! His videos are incredibly entertaining and educational for people of all ages. And there are study guides that come with them. We watch them with the whole family and they hold the attention of even the littlest (down to say 4 yo) while all of us learn new things as well. Highly recommended ...

This sounds taylor made for the Catholcism 101 forum.

I would also recommend John Henry Newman.

There's a huge library of Mr. Ray's essays here, too. Good, solid stuff.

Well, since my favorite was already noted (Theology and Sanity by Sheed), I'd also suggest the Surprised by Truth series.
