I am trying to find Heracleon’s Commentary on John. I know Origen quoted Heracleon’s Commentary on John but I can only find a source in the Logos catalog on its website for fragments. What is the deal here?
Not doing your research, but for others on Heracleon's influence on the Logos vs creation (late 2nd Temple theology):
From FOC - Origen etc:
"(39) None of Heracleon’s writings have been preserved except for forty-eight fragments quoted in Origen’s Commentary on John, two fragments quoted by Clement of Alexandria, and an allusion to a viewpoint of Heracleon in Photius."
"(45) While there are eight, and possibly nine or ten, Greek manuscripts containing the Commentary on John, they are all dependent on one thirteenth century manuscript Codex Monacensis 191 (M) which is located in Munich. This dependence on Codex Monacensis has been established by A. E. Brooke and E. Preuschen,125 and is accepted by C. Blanc in the only critical edition of the commentary to appear after the editions of Brooke and Preuschen. This means that our knowledge of the text of the commentary is completely dependent on this one manuscript."
and
"These fragments are published in The Fragments of Heracleon, ed. A. E. Brooke, vol. 1 no. 4 of Texts and Studies, ed. J. A. Robinson (Cambridge [England]: University Press, 1891), 1–112. On Heracleon, see also C. Gianotto, “Heracleon,” EEC 1.374; Rudolph Gnosis 17, 323–24."

Is discussed in depth in Ante-Nicene Fathers v9 Orig., Comm. Jo. 2.8 ... if you have it.
