When you look at the history of how the book we know as The Bible came to be it raises some serious red flags. All of these "small books" were written by many different authors over a period of time. Then, centuries after all of these books and letters were written, a council of men sat down and came up with the cannon. So, some books were put into the Bible and other were purposely left out.
Were any of the books left out allegedly inspired?
Were any of the books put in not inspired?
Who knows?
Who cares?
