Is there any systematic plan or process to update the New City Press Augustine edition with new volumes?
Volume 44 was released in November 2020 but I have not seen any sign of it on the Logos website.
You can vote for volume 44 here: https://feedback.faithlife.com/boards/logos-book-requests/posts/augustine-ncp-homilies-on-john-41-124
Also, I would be all for Logos acquiring the NCP translation of Instructing Beginners in Faith (Lat De catechizendis rudibus), which will appear in a forthcoming volume of the Collected Works with a number of other texts.
