'Book of the Chronicles' in the Bible

And, when the thing was searched into and found true , then were they two hanged upon the gallows, and it was written, in the book of the chronicles, before the king.

But, all the acts of his authority, and his might, and the clear story of the promotion of Mordecai, wherewith the king promoted him, are, they, not written in the book of the chronicles of the kings of Media and Persia?
