Series IV. Lecture notes, sermons, teaching materials, drafts of published works, articles, etc. (boxes 38-109)

This series includes course lectures and notes from Tillich's teaching at Union Theological Seminary, Columbia University, Harvard Divinity School, and the University of Chicago. Course names and lecture titles are included when available. This series also contains material related to Tillich's published writings. There are handwritten versions and typescripts, usually annotated, of some of his best known works such as Systematic Theology. The Gifford Lectures, which served as the basis of Systematic Theology, are also included. The Gifford Lectures are comprised of three series of ten lectures each. The first series ("Existence and the Christ") and second series ("Life and the Spirit") are complete with all lectures. The third series ("History and the Kingdom of God") was never given and consists of only a short outline of the lectures.

Also included are drafts of works such as Love, Power, and Justice, The Courage to Be, Dynamics of Faith, and Biblical Religion and the Search for Ultimate Reality. There are also several collections of Tillich's sermons, such as Shaking of the Foundations, New Being, and Eternal Now. The series also contains a varied mix of articles, lectures, symposium papers, travel reports, and chapters written by Tillich which were contributions to others' works. Box 507 contains Dialogue With Tillich, compiled by D. MacKenzie Brown, which is the result of a seminar Tillich gave at the University of California, Santa Barbara, in the spring of 1963. Finally, the series contains book reviews written by Tillich, as well as a travel diary written in 1936 and published posthumously in 1970 under the title My Travel Diary: Between Two Worlds.
