It is not at all surprising that there is a vast academic industry of Sappho studies. In the past I’ve covered a number of excellent, detailed publications that speak directly to the historic and social context of Sappho’s life and work, especially as it speaks to female same-sex relations. (Or to the reception of her life and work in other eras.) So I’ve gotten past the point of trying to include every Sappho publication I run across in someone’s bibliography, unless it looks like it might add to my existing coverage.
