The Church History courses I took while creating this timeline were taught by Dr. David Calhoun (author of History of Princeton Seminary) and the text was The Story of Christianity by Justo Gonzalez.
Dictionary of the Christian Church is a reference I used and found helpful while creating the timeline.
Other books on this list are mentioned in the timeline, or the authors are in the timeline, or I thought they looked interesting.

Selected Writings: Thomas Aquinas
By Translated by Ralph McInerny / Penguin Putnam Inc.
Although a controversial figure in his own day, St. Thomas Aquinas (c. 1225-74) forged a unique synthesis of faith and reason, of ancient philosophy and sacred scripture, which decisively influenced Dante and the whole subsequent Catholic tradition.
Intensely interested in Aristotle, as well as Plato, Paul, and Augustine, Thomas believed that unaided human thought can take us a long way towards wisdom and truth, although it must always be supplemented by the central mystery of revelation. His writings contain many classic statements of doctrine about angels, the Incarnation, Trinity, sacraments and the soul and also penetrating discussions on choice, creation and conscience, law, logic and the purpose of life.
In this superb selection, arranged chronologically, Ralph McInerny brings together sermons, commentaries, responses to criticism and substantial extracts from one of Christianity's supreme masterpieces, the Summa theologiae. For anyone concerned to find ways of reconciling science and dogma, reason and religion, Thomas has always been a major source of inspiration. This volumes reveals both the development and the sheer scope of his work.

This modern translation is direct and concise, yet retains a deep devotional flavor.
The Practice of the Presence of God
By Brother Lawrence / Baker

How does a person relate to God, to other people, and to the world around? This classic expression of the Reformed faith offers six lectures on Calvinism. Abraham Kuyper introduces Calvinism as a life-system, discusses its relationship to religion, politics, science, and art. Though these lecture were delivered at Princeton in 1898, what Kuyper says is not of historical interest alone; it has relevance for today.

Christ and Culture
By H. Richard Niebuhr / Harpercollins Publishing
