This is a partial list of the books I've used in editing on the topics shown.
I recently edited this page and found it humbling to consider the large number of well-known books I have not read. Sigh.
I am fantastically lucky that the real person who is Opus33 has access to an excellent library, which offers its users access to millions of books and many for-pay scholarly websites. The world needs to be changed to make personal research (like writing WP articles) open to all, at the same time paying editors and publishers for the valuable work they perform. It's a hard problem.
