For those interested:
A summary of biblical and secular evidence for Jerusalem's destruction in 587 BC can be found in Jack Finegan’s Handbook of Biblical Chronology: Principles of Time Reckoning in the Ancient World and Problems of Chronology in the Bible (Revised Edition, Hendrickson Publishers, 1998).
A classic work on biblical chronology is Edwin R. Thiele’s The Mysterious Numbers of the Hebrew Kings (New Revised Edition, Kregel Publications, Grand Rapids, Michigan, 1994; Zondervan Publishing House, 1983; various editions back to 1951).
A comprehensive debunking of the Society’s scriptural claims, along with some secular material, is available at “Jeffro’s 607 pages.” This includes detailed debunkings of recent Watchtower articles:
