I am studying the Dead Sea Scrolls a bit. I have read the Factbook entry on the Dead Sea Scrolls, The Dead Sea Scrolls and the Bible by Charles F. Pfeiffer, The Meaning of the Dead Sea Scrolls by James C. VanderKam; Peter W. Flint, What are the Dead Sea Scrolls and Why Do They Matter? by David Noel Freedman, Pam Fox Kuhlken, and pertinent portions of The Resurrection of the Son of God by N. T. Wright. I am looking to study what these scrolls reveal about the historicity of the Bible as well as who the Qumran community was composed of as far as ethnicity. What sources do you all suggest?
