I once wrote about the Jacob (pseud)epigraphon in the book of Alma, which I said I would follow up on but never did, and I won’t do it here. Because there are even more Old Testament pseudepigrapha to write about that are not old but new!
The current issue of the Ensign features an article written in the first person as though by Adam. It looks to be the initial article in a series called “Old Testament Prophets,” coinciding with the year’s gospel doctrine topic. Apparently, soon there will be articles written by Enoch, Noah, and so forth.
The differences may well be extensive. They should not merely be assumed, however. They should be reflected upon and verbalized.
