The Neal A.
Maxwell Institute (PKA Foundation for Ancient Research and Mormon Studies) has
recently posted a number of the FARMS Preliminary Reports, dating from the
1970s onwards, researched and written when FARMS (now NAMI) focused a lot of their attention on the historicity of the Book of Mormon.
One highly
recommended one (actually two in one) offering would be this link that contains
two important studies by John A. Tvedtnes, “Hebraisms in the Book of Mormon”
and “The Isaiah Variants in the Book of Mormon.”
