Why do Mormons use the Protestant Canon of The Bible?

I do find it interesting that Joseph Smith claims that the the Early Church went apostate soon after the death of the last Apostle, but used the same Canon of the Bible as the Protestants (with the exception of the Book of Mormon, Doctrine and Covenants, and Pearl of Great Price, etc.) I would love to know how he came to this conclusion.

I started reading some of the Mormon Scriptures and plan to finish, and I do recall Joseph Smith railing about how much he did not like the Methodists. My guess is that he got his Canon of the Bible form the reformers, but this is just speculation on my part.

If there is a knowledgeable LDS individual who can help clarify this for me, I would greatly appreciate it.

I saw in another forum, someone recommend the book titled, “The King James Bible and the Restoration.” I will have to check that out.
