Here are the books, studies and other works I've used in my articles. They're not direct recommendations, just perspectives I've used in my writing. I hope they help you to dive deeper into topics you find interesting.
Why Bookshop.org?
Firstly, because it's not Amazon. Second, because it supports local bookshops. If it's not available in your area, I'm sorry. I'd still like to ask you to consider buying the book you're interested in from a local bookshop in your area.
