Introduction to Historical Theology: The Venerable Bede

This encyclopedia is particularly good at emphasizing the links between various theologians and theological movements (e.g., who influenced whom, etc.) It is quite comprehensive, comprising 10 volumes total.

Vol. 1 of the Loeb Classical Edition. This is Bede's Ecclesiastical History, his most well-known work. The Loeb edition features the original Latin and the English on facing pages, which makes it easy to study.

Vol. 2 of the Loeb Classical Library edition. Contains the rest of Bede's Ecclesiastical History, as well as his Lives of the Abbots and Letter to Egbert.
