Thanks Peacefulpete. Good info.
The J, E, P, D has largely been replaced by R and D these days with almost no layperson materials yet updated with this, even though this is now the norm for about 30 years or so in modern documentary studies.
What happened was after the Qumran scrolls were discovered, it became clear that there was clearly a redactor, but since the Masoretic theories were far more correct than the Christian methodologies that created the Document Hypothesis it was revised using Jewish critical studies (which were largely ignored).
While the new hypothesis recognized the "possibility" of J, E, and P, it notes that it is more likely that a school of redaction influenced by the Babylonian exile created everything outside of D. So everything is now divided into simply R and D, with R being made up of possibly many sources, but in the end under a central type of redactor of some sort, likely a school of scribes working over a generation, possibly under a great scholar or Jewish prophet.
The latest edition of the NRSV Updated Edition SBL Study Edition from HarperOne is the first new layperson book I've seen with anything close to some of this new data from the past few decades--except it only touches on the New Testament. It published (finally) that scholars no longer hold to the Q theory. It will take another 10 years before the last 30 years of scholary work finally trickles down to study Bibles (and who knows how long before it hits Wikipedia).
