Need to find some Greek text out of Migne? Here are a few good places to check.
- The Religion and Technology site has a complete index of PG. (Just a list of volumes. No texts, though you can buy their DVDs.)
- In addition to loads of other online links (including PL) to books related to the Bible, Judaism, and Christianity, Mischa Hooker has compiled links to PG volumes available through Google Books. Note that the Google Books version of PG are PDF image files. (You can get "plain text," but you won't be able to read the Greek.)
- "Roads of Faith - Digital Patrology" is a site that is composed in Greek, but it has a very large collection of the PG volumes organized by periods or alphabetically by author. These are PDF files, but they are actual Unicode text. [UPDATE: 2008.07.06: The Roads of Faith site seems to regularly go offline. Try again later...]
- UPDATE 2008.07.06: As noted in the Kent (from Logos),Logos Bible Software recently announced work on the first twenty volumes of the Patrologia Cursus Completus, Series Graeca. At this time it is on prepub for $400, and as a Libronix doc, it will have the benefit of being cross-linked with other resources. (E.g., with English translations, but I don't think we should expect it to be morphologically tagged!) There is a nice description of the contents of these 20 volumes on the prepub page, and Rick Brannan provides a full table of contents here in PDF.
