This morning I’ve been poking around the PDF volumes of the Patrologia Graeca. I was trying to find the Lexicon of Photius, in fact.
I’ve not achieved much, because it’s quite hard to work out which volumes contain what. Each volume does contain a table of contents; but you have to download and open the PDF to see it. Some of the volumes are in 1900 reprints, which I can’t access anyway.
It seems to me that someone needs to go through the PDF volumes and type up a table of contents for each, and put it online. There’s only 161 of them, and the task might take a day or two. I was a little tempted myself, in truth.
