I have the "KJV Apocrypha" book. The KJV today however does not have those eight books. Did the first KJV include more than it does today?
All KJV Bibles printed before 1666 contained the Apocrypha.
One other detail remains to be mentioned. In 1666 appeared the first edition of the Authorized Version from which the Apocrypha was omitted. It had previously been omitted from some editions of the Geneva Bible, from 1599 onwards. The Nonconformists took much objection to it, and in 1664 the Long Parliament forbade the reading of lessons from it in public; but the lectionary of the English Church always included lessons from it. The example of omission was followed in many editions subsequently. The first edition printed in America (apart from a surreptitious edition of 1752), in 1782, is without it. In 1826 the British and Foreign Bible Society, which has been one of the principal agents in the circulation of the Scriptures throughout the world, decided never in the future to print or circulate copies containing the Apocrypha; and this decision has been carried into effect ever since.
