Special Collections at the Yale Divinity School Library include more than 6000 linear feet of archival material, archivally-treated pamphlet collections, and microform holdings. In 2017, the Divinity Library added numerous collections that were previously held by Andover Newton Theological School.

Particular strengths of the collection are its documentation of the Protestant missionary endeavor, religious work among college and university students, and records related to American clergy and evangelists. The Divinity Library holds personal papers of numerous faculty members and a collection of memorabilia and publications related to life at Yale Divinity School, but the official archives of the Divinity School are deposited in the Yale University Archives.
