From Richard Baxter’s A Christian Directory, Chapter 2, Part 1, page 56,

“Make careful choice of the books which you read. Let the holy Scriptures ever have the pre-eminence; and next them, the solid, lively, heavenly treatises, which best expound and apply the Scriptures; and next those, the credible histories, especially of the church, and tractates upon inferior sciences and arts: but take heed of the poison of the writings of false teachers, which would corrupt your understanding; and vain romances, play-books, and false stories, which may bewitch your fantasies, and corrupt your hearts.
Let Scriptures be first and most in your hearts  and hands, and other books be used as subservient to it.”
