The Coptic Apocalypse of Peter: Nag-Hammadi-Codex VII,3: Texte Und Untersuchungen Zur Geschichte Der Altchristlichen Literatur, cartea 144

As an accompaniment to the corpus of the Griechischen Christlichen Schriftsteller (GCS), Adolf von Harnack created the monograph series Texte und Untersuchungen zur Geschichte der altchristlichen Literatur (TU) in 1882, which from that time on served as an archive for the ... editions of older Christian writers . Still today, the series includes especially the old translations of the works published in the corpus some in their original language, some in German or in another modern language. Moreover, the series is also open to preliminary studies of the editions and accompanying reviews."
