The Corpus Scriptorum Ecclesiasticorum Latinorum (CSEL) is a series of critical editions of the Latin Church Fathers published by a committee of the Austrian Academy of Sciences.
The CSEL is intended to include the ecclesiastical authors who wrote in Latin from the late 2nd century AD until the death of Bede in 735. The texts are edited on the basis of all extant manuscripts and according to the principles of modern textual criticism and thus aim to provide a critical replacement for the corresponding volumes of the Patrologia Latina.
