Kindly, Antesi, from the Patrologia Group, has notified me about the project mantained by the Orthoblog project related to the BEPES series.
The first volumes are being shared like pdf files, with a good quality and full color. The list does not include the 3, 13, 55, and 88 volumes.
Note from 08 Nov. 2009: the first version in pdf was replaced by .djvu files, which have each one few mb size’s.
