The latest volume of the venerable REJ is now available online
. It includes an article
by Dr M Morgenstern on the textual value of the Yemenite manuscripts of the Babylonian Talmud. Morgenstern is working on a comprehensive grammar of Jewish Babylonian Aramaic, based primarily on Oriental manuscripts (of the Talmud and the Geonic literature) and on magic bowls. His conclusion in this article is that from a linguistic perspective, the Yemenite manuscripts are contaminated by outside influences, and sometimes are simply mistaken.
Correction: Dr Morgenstern pointed out to me that he was discussing the Yemenite reading tradition, not necessarily the text of Yemenite manuscripts.
