Jeff Lindsay wrote a very useful review of John Sorenson’s book “Mormon’s Codex” on his blog, Mormanity. As we as Mormons believe the Book of Mormon to be a true record by people who lived in the Americas between 600 BC and about 350 AD, theoretically, archaeological findings should generally align with certain details in the Book of Mormon. This has been somewhat problematic in the past, partly, it seems, due to relatively limited studies of the peoples and sites of Central America (compared to, say studies of Israel or Egypt.) Sorenson seems to indicate that new studies are starting to have more and more potential points of agreement.
