What a great overview! I read
Odd Girl Out in its entirety a few years ago and was pretty disappointed - not much of what I'd hoped for from a pulp: good setting/feel for the time period and lots of sex; it is really pretty formulaic. So this overview was a nice surprise.
Some of the selections in this book are pretty bad,but most are not. They're often interesting explorations of women coming to terms with their sexuality in mid-20th century America and some have a really fantastic sense of place and time. (Okay, yeah, the sex scenes are pretty fun too!)
The bibliography and list of other lesbian-related literature is also helpful for adding to one's book list.
