Ad Fontesto the sources

Guide to Reliable Editions

101 authors: the standard critical edition for each, what Ad Fontes itself uses, and where the two differ.

Two honest facts shape this guide. First, the texts on this site are mostly public-domain editions and translations, which means mostly 19th- and early-20th-century work: readable and complete in most cases, but dated, and in places a selection rather than the whole author. Second, the standard critical editions named below are usually still in copyright and are not reproduced here — this guide tells you which book to consult, and the work pages tell you what this site actually prints, so the difference is never hidden.

The series, in short

Partial or older translations — read honestly

The clearest cases: Philo in Yonge (1854-55) and Josephus in Whiston (1737) are the only complete public-domain English versions, and both read their age; the Loeb editions are the modern replacements. The Fathers in ANF/NPNF are 19th-century translations, and for Ephrem, Aphrahat, and Cyril the site prints selections or surviving fragments, as the work pages state. The Greek and Latin classics come from the Perseus Digital Library, whose English translations are likewise mostly 19th-century; the original-language texts are the critical texts of Perseus's day, not the newest OCT or Teubner revisions. Where a work survives only in quotations by another author — Hegesippus, Aristobulus, Celsus, and the other fragmentary writers — the work page says so, and no complete text is pretended.
