I want something like this, I don't know if it exists yet, but I think it'd be neat:
1 Nephi: Nephi -> Joseph Smith (translator)
2 Nephi: Nephi -> Joseph Smith (translator)
...
Zenos (Jacob 5): Zenos -> Jacob (transcriber)? -> Joseph Smith
...
Mosiah: Mosiah -> Mormon (abridged) -> Joseph Smith (translator)
Zeniff (Mosiah 9-22): Zeniff -> Mosiah (scribe)? -> Mormon (scribe)? -> Joseph Smith (translator)
Alma (Mosiah 22-23): Alma -> Mosiah (abridged)? -> Mormon (abridged)? -> Joseph Smith (translator)
Ether: Ether -> Moroni (abridged) -> Joseph Smith (translator)
Basically, the "lineage" of all the different authors' works in the Book of Mormon (as such is manifest in the book itself), from the time they were originally written to the time that Joseph Smith translated them into English. The idea here is to document all the hands involved and their role. So, for instance, Zeniff's account in the book of Mosiah reads like it was essentially added directly into the plates, so the "lineage" could go Zeniff -> Joseph Smith (translator). However, it appears in the middle of the book of Mosiah, and it's entirely possible that it was copied onto the plates by Mormon, in which case we'd have Zeniff -> Mormon (scribe) -> Joseph Smith (translator). Further, it's possible that Mormon simply transcribed what Mosiah had written at that point in his record, so really the lineage would look like: Zeniff -> Mosiah (scribe) -> Mormon (scribe) -> Joseph Smith (translator). Thus I have it listed above with question marks as, so far anyways, I haven't found a clear indication of exactly how Zeniff's record was physically added to the Book of Mormon.
I guess I've kind of started this above, so perhaps I'll finish it (someday) if I can't find a preexisting version someplace.
