While creating a basic Wikipedia article on the Arian bishop Patrophilus of Scythopolis I stumbled across the fact that someone has placed a scanned version of Wace’s Dictionary of Christian Biography to the end of the Sixth Century in Wikisource. This is invaluable for obscure patristic writers, as every statement tends to be referenced to the primary sources. The article on Eusebius of Emesa was useful; all the ‘E’ writers are here.
