It may seem odd that there would be a book inside of the Book of Mormon titled "the Book of Mormon" but Mormon was a prophet just like any of the other prophets and was entitled to write his own account just as they had. He didn't know, at the time, that he would end up writing a larger abridgment of the entire record as well.
His own record was a tragic account of the total destruction of his people and the horrible scenes that he was unavoidably made to observe. This is a sad tale but one that is important to learn if we are to avoid the same fate they suffered. So gird up your loins and have a listen.
