To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
A nice little resource. Sadly it was only published once, so it's way out of date and ends with a few books published in 1993.
Divided by theme, there are blurbs from a panel of contributors (all female) about 500 books: everything from Autobiography/memoir to oral histories, novels and nonfiction.
There are cross-referenced indices and lists at the beginning of every theme. Included are lists of books by women of color living in the US and a "list of some books about lesbian and gay people." Clearly time has not been kind to this particular listing, and that's the issue. The areas covered are way too broad, the 1990s overrepresented and marginalized people are just barely creeping into consciousness in 1993-94.
I truly wish someone would update this particular reference, but until then it's handy for finding books and authors I may otherwise have missed.
