Two scholarly articles worth knowing about are 1) M.L. West's "Erinna" from Zeitschrift für Papyrologie und Epigraphik, 1977, Bd. 25 (1977), pp. 95-119. Though at the article's end West can't bring himself to see that Erinna, a woman, wrote this poem. Alas. 2) John Rauk's "Erinna's Distaff and Sappho Fr. 94" Greek, Roman and Byzantine Studies; Cambridge, Mass., etc. Vol. 30, Iss. 1, (Jan 1, 1989): 101 ff. You'll find the Greek text in both articles.
