The Resurrection of the Son of God (Christian Origins and the Question of God, Vol. 3)

This is a great reference book with almost everything you may want to know about the resurrection. Tends to be rather difficult reading, but its clear that NT Wright knows his stuff.

Very thick reading.

every pastor should read this before preaching on Easter. although at almost 800 dense, footnoted pages, he should start right after Christmas.

Wright details both Biblical and extra-biblical evidence for the historicity of Jesus' ressurrection. This is a pretty scholarly and lengthy examination of the topic; there are easier reads out there, but this one is impeccably documented.
