Volume 4 of the Critical Text Project represents the central task of the Dr. Skousen's effort, which is to recover the original English-language text of the Book of Mormon. Dr. Skousen is an internationally known professor of linguistics and English language at Brigham Young University and has been the editor of the Book of Mormon Critical Text Project since 1988. Part 5 of volume 4 (analyzing Alma 56 to 3 Nephi 18) examines 906 cases of variation (or potential variation) in the text.
For 349 of these cases, the critical text proposes readings that differ from the standard text (the current edition). Of these proposed alternate readings, 100 have never appeared in any standard printed edition of the Book of Mormon while 27 readings make a difference in meaning that would show up in any translation of the English text of the Book of Mormon into another language.
In addition, 17 readings make the text fully consistent in phraseology or usage, while 2 readings restore a unique phrase or word choice to the text.
