I'm just curious why you hold that belief? I don't have an opinion either way, but I'm curious if that is an informed belief.
I agree that it was a problem even more recently than a century ago. It was probably a problem as recently as 10 years ago. However, in 2017, it's not hard to be published. You can even self-publish.
Unless the topic is related to the author's identity (i.e. it's about gender, race, sexual orientation, nationality, etc.), I don't see why someone should care about the identity of an author.
Take "The Death and Life of Great American Cities" on your list. Why does the gender of the author matter for such a topic? Books are written by individuals not demographics.
This is a genuine question and not an attempt to troll. I don't understand why gender or any other identity needs to be a concern aspects where it is orthogonal/unrelated.
