This list contains books that:
- have at least two women in them,
- who talk to each other,
- about something other than a man.
Wikipedia has a decent intro on the origins of the metric: en.wikipedia.org/wiki/Bechdel_test
Beware that this test is very limited in probative value. "The Bechdel test only indicates whether women are present in a work of fiction to a certain degree. A work may pass the test and still contain sexist content, and a work with prominent female characters may fail the test." This is just one thing a person may want to consider in their reading. There are many others.
I (@kingrat@sfba.club) track this in my reading as a check to make sure I am including reading that includes non-token female characters because American publishing often overly focuses on men's stories, and that is quite often reflected even more strongly in what American men choose to read.
