I would be grateful for an explanation of how to correctly cite the Nag Hammadi texts. I could not find a manual on google, perhaps I typed wrong words in the search.

I paste a few fragments which I need to quote, supplemented by my "numbering" of the reference below, which is most surely incorrect. I also added a page number from Robinson's translation.

1. “[i]t is I who am God; there is none [apart from me].”

NHC II, 86, 30–31, James M. Robinson, ed., “The Hypostasis of the Archons (II,4),” in The Nag Hammadi Library in English, trans. Bentley Layton, 3rd ed. (San Francisco, CA: Harper and Row, 2000), 162.

2. “the archons took him and placed him in paradise. And they said to him, ‘Eat, that is at leisure,’ for their luxury is bitter and their beauty is depraved. And their luxury is deception and their trees are godlessness and their fruit is deadly poison and their promise is death.”

NHC II, 21, 17–24, James M. Robinson, ed., “The Apocryphon of John (II,1, III,1, IV,1, and BG 8502,2),” in The Nag Hammadi Library in English, trans. Frederik Wisse, 117.

3. “[t]his time he planned to bring a flood upon the work of man,”

NHC II, 28, 34–35, Robinson, “The Apocryphon of John,” 121.

4. “Come, let us cause a deluge with our hands and obliterate all flesh, from man to beast.”

NHC II, 92, 5–8, Robinson, “The Hypostasis of the Archons,” 166.
