"A sound study-library must be a top priority. For many, such a library has been unimportant and the result has been an impoverished ministry, lacking depth, breadth, and stimulation. An excellent library is constructed by deliberate acquisition rather than "accidental" accumulation. Since an expository preacher's library is an integral part of his pulpit work, it should be assembled with an eye toward the highest quality.4 A preliminary indication of what a core library is not will help understand what it should be: 1. It is not a collection of inferior books donated to the preacher by well-meaning friends and listeners. 2. It is not an accumulation of books offered on sale or at discount prices. 3. It is not simply a collection of materials that are highly recommended or found on standard lists of bibliographies."
