Royal Skousen’s The Book of Mormon: The Earliest Text was published by Yale University Press in hardback in 2009. This text represents the culmination of 25 years worth of study of the Book of Mormon manuscripts (both what remains of the original manuscript and the printer’s copy).
This wonderful resource is now also available in a Print Replica Kindle edition. The print edition represented the text in sense-lines, or phrases that marked the important concepts. This is an important way to read the text of the manuscript that was dictated without punctuation. The Kindle edition is an exact reproduction of the print version, with the same sense-lines and the same typefaces.
