When I was a kid I said, “…a box of Book of Mormons…” Then my smart sister taught me that it’s the “book” that’s plural, not the “Mormons”. So then I thought I was smart to go around saying, “…a bushel of Books of Mormon…”. With this supreme intelligence in hand I once tried to correct a Mormon journalist when he printed “…an bundle of Book of Mormons…” He promptly corrected me and explained that “The Book of Mormon” is a title of a book, the word “book” is a part of the title. Therefore, it is correct to say, “…a billion Book of Mormons…”
Is he right?
