Lesbian philosophy Book

Obsolete book published in 1975 that describes a bunch of lesbian writers and the novels they wrote, from the late 19th and earth 20th centuries - think Colette, Gertrude Stein, Virginia Woolf, Natalie Barney, et al. It was depressing to read about them, because they were so full of self-loathing and hatred for the whole lesbian condition. Then she goes on to describe the state of the lesbian world as it currently was in the mid-1970s. All I can say is I am SO glad I was just a little girl then and not able to come out. How depressing.
