- 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. A handful and useful list provided by P. Stefan Zara here.

- Albertus Magnus Opera Omnia [Borgnet Editio]. Albert the Great (ca. 1200 – 1280) is one of the most important medieval philosophers and theologians, yet his thought remains as a whole relatively understudied. This can be explained by a variety of philosophical and historical reasons, but purely « material » factors are also at play. There is indeed no truly complete edition of his works, and the age and the rarity of the most complete one (Opera omnia, ed. A. Borgnet, 1890-1899) render it hard to access for many scholars. The new critical edition (sometimes called Editio Coloniensis), begun in 1951 and very competently led by the Albertus-Magnus-Institut of Bonn, offers a much more reliable text but will not be completed before many more decades and its high cost means that not all university libraries — including in North America and in Western Europe — can afford a subscription to it. In addition, the impressive number of Albert’s works, as well as the huge size of many of them, lead one quickly to dream of the day when the critical edition will be completed and made available electronically. [Other list, with the same edition but over the GoogleBooks project, is being mantained by Martin D’Ascenzo here.]
