Plan of the summary by books and volumes
Epiphanius is opening his summary by explaining how he will lay out the count of the eighty heresies across the books and volumes of his work.
Epiphanius writes: And returning again, I will divide them by book and show in this summary how many of these eighty heresies are in the first book, then in order in the second, and through to the third. I will also show, for each of the seven volumes arranged within the three books, how many heresies each one contains. It is as follows: the first book has three volumes and forty-six heresies, with their names—I mean Barbarism, Scythianism, Hellenism, Judaism, and Samaritanism. list continues The second book has two volumes and twenty-three heresies. The third book has two volumes and eleven heresies. So in the first book, the first volume contains twenty heresies, which are these: Barbarism, Scythianism, Hellenism, Judaism.

Ἐπανιὼν δὲ αὖθις, καὶ διελὼν ταύτας κατὰ βιβλίον, ὑποδείξω ἐν ταύτῃ μου τῇ ἀνακεφαλαιώσει, πόσαι τούτων τῶν ὀγδοήκοντα αἱρέσεων ἐν τῷ πρώτῳ βιβλίῳ, καὶ καθεξῆς ἐν τῷ δευτέρῳ, ἕως τοῦ τρίτου· ἀλλὰ καὶ καθ᾽ ἕκαστον τῶν ἑπτὰ τόμων, τῶν ἐν τοῖς τρισὶ βιβλίοις συντεταγμένων, πόσαι εἰσὶν αἱ ἐν αὐτῷ χωρηθεῖσαι αἱρέσεις. Καὶ ἔστιν οὕτως· ἐν μὲν τῷ πρώτῳ βιβλίῳ τόμοι τρεῖς, αἱρέσεις δὲ τεσσαρακονταὲξ σὺν ταῖς ὀνομασίαις τούτων· φημὶ δὲ Βαρβαρισμοῦ, καὶ Σκυθισμοῦ, καὶ Ἑλληνισμοῦ, καὶ Ἰουδαϊσμοῦ καὶ Σαμαρειτισμοῦ· ἐν δὲ τῷ δευτέρῳ βιβλίῳ τόμοι δύο, αἱρέσεις εἰκοσιτρεῖς· ἐν δὲ τῷ τρίτῳ βιβλίῳ τόμοι δύο, αἱρέσεις ἕνδεκα. Ἐν τῷ οὖν πρώτῳ βιβλίῳ πρώτου τόμου αἱρέσεις εἴκοσιν, αἵ εἰσιν αἵδε· Βαρβαρισμός, Σκυθισμός, Ἑλληνισμός, Ἰουδαϊσμός.
