The appendix has a useful chart that separates the biblical verses by source and also includes a bibliography of major scholarly works on biblical history. He also traces what he believes to be the J source through several other books of the bible. Although this extended view of J has not yet received general acceptance among scholars, Friedman is a highly respected scholar in the field of source criticism and his views carry some weight. There are also numerous scholarly commentaries on each book of the bible and several of the commentaries discuss the role of the J, E, P and D sources on the first five books. One of the better reference works in this area is the Anchor Bible, which consists of a separate volume for each book of the bible, with translation and commentary by a leading scholar on the volume in question.
Bible dictionaries provide a good way to get fast information on a particular person or topic.
One of the best is the seven volume Anchor Bible Dictionary, which contains many scholarly commentaries by leading experts in biblical studies. Released only a few years ago, it not only contains some of the latest information on archaeological sites in the Near East but in many areas of study summarizes the competing views of several scholars on a particular topic. It also has the advantage of being separately released on CD-Rom. Other useful bible dictionaries include the Harper Collins Bible Dictionary, edited by Paul C. Achtmeier in conjunction with the Society of Biblical Literature, one of the leading organizations for biblical scholars, and the Harper's Bible Dictionary edited by Madeleine S. and J. Lane Miller. In addition, many of these bible study packages offer integrated reference works, including Strong's word concordance, Hebrew and Greek dictionaries with definitions, bible dictionaries and a bible Atlas.
