..get copies of them from?
An archaeological site near the Dead Sea... ;)
Nah, seriously though.. I dunno. But I'd be interested in the answer too. I've seen some loonies peddling what they called the original Bible/Torah, or parts of it at least.. but those have always been cultist nuts that rewrote the existing books to legitimize their claims.
Kinda unrelated.. but if you’re just interested in the history of the era, this blog usually has decent info keeping up with the latest news: “A weblog on ancient Judaism and its context”](http://paleojudaica.blogspot.com/)
if you go to history channel website, u may find manuscripts of a program aired recently titled banned from bible which has various books which were notincluded in the bible in its current form, some of these are part of the dead sea scrolls. there were variosu reasons including duplication of narration, questions about the authenticity etc.but take a look.
I hear the Gospel of Barnabas (banned by the Nicene council around 325 C.E. ) is somewhere close to the real message Jesus preached.. rest is all the new religion created by Paul by massaging Pagan Roman religion and platonic philosophy..
.. not much different than what happened to Islam a hundred years after the Qur'an.
