John Sorenson assembled the material under the title,
The Geography of Book of Mormon Events: A Sourcebook
This remains the single best collection of the various geography theories and I recommend it. I refer to it often and cite it in some of my books.
As I always try to emphasize, John Sorenson is an excellent scholar, as this sourcebook shows. Here's his response to an important question:
I completely disagree with Sorenson here, not just because he got a date wrong, but because I wouldn't characterize Benjamin Winchester as a "close associate" in a positive sense. In my view, what Joseph learned from Moroni was more comprehensive than "preliminary hunches" and I think Joseph was pretty clear about that--even after reading the Stephens book when he wrote the Wentworth letter and edited out Orson Pratt's hemispheric/Mesoamerican theory.
But still, Sorenson has done some very helpful research. One must use critical thinking in evaluating his work (as well as the work of anyone else).
