On the subscription version of the site this page has an A - Z index of authors from the first five centuries. Virtually all of first to fifth centuries authors from the Migne Patrologia series are covered with links to the complete text (scanned text e.g. at Google Books). English translations (published and online) are listed where they have been found and can be seen alongside the original language. The indexing system makes it very easy to match original language texts and translations. There is also an index of biblical (and some apocryphal) books listing commentaries, homilies etc. which were written on them during the first five centuries. Again the original language text (scanned text e.g. at Google Books) can be seen alongside online English translations (where found).
