Yes, I would definitely like to see some of his stuff.

These were written during WWI or II for the most part, Mere Christianity were originally radio addresses given by lewis during bombing raids and other wartime calamity (or so I think.) and as such are probably not yet in the public domain. I've read Screwtape Letters, it's a wonderful little bit of theology and a great mental exercise, I've got to pick up a copy of Mere Christianity.

Lewis' magum opus is his Space Trilogy (Out of the Silent Planet, Perelandra, That Hideous Strength). They are sort of The Chronicles of Narnia for adults. Most of Lewis's stuff is worth reading (even if I disagree with his theology), but it is not yet in the public domain.

Yes--C.S. Lewis's work is still copyrighted, but we're compiling a list of "classics" that are still under copyright so we can look into licensing them. We'll add Lewis to our list.
