Below, are some of the books I own that William Lane Craig authored or co-authored. They are all great books, and I highly recommend them. These are not all that I have read from Bill Craig. I have also read many articles and heard him publicly debate as well. His website has a wealth of information.
Reasonable Faith - By William Lane Craig
Philosophical Foundations for a Christian Worldview - By J.P. Moreland and William Lane Craig. A huge, fascinating book, and a great resource. I highly recommend it.
The Son Rises - The Historical Evidence for the Resurrection of Jesus. By William Lane Craig. A smaller book, excellent.
On Guard. Defending Your Faith with Reason and Precision. By William Lane Craig
