I know about the Book of Enoch, have yet to read it, but I know there are several other books that were not put in the final version.
I’ve also heard some grumbling about King James himself and his role so since there are many Bible wise Annons on this site, hoping you will share your knowledge.
There is the Doay-Rheims Bible which was translated from the Vulgate Bible written in 395AD by Saint Jerome, this bible was published in 1610.

The Geneva Bible of 1560 accompanied the founders of America on the journey over the Atlantic on the Mayflower and was most probably the one used by Shakespeare when writing his plays. There are a lot of translations and revisions of this dating to around 1599.

The Gospel of Barnabas is worth a read as is the Nag Hammadi library which was discovered in 1945, this is a Gnostic Bible.
There is a lot of controversy surrounding these two tracts.
