The provided text outlines the methodology for compiling a list of non-fiction writers who have dedicated Wikipedia pages. It specifies that the list encompasses authors from a wide array of non-fiction fields and includes individuals with published non-fiction works. The criteria for inclusion stipulate that authors must possess their own Wikipedia page, and if a single book is used to exemplify their work, that book must also have a dedicated Wikipedia page. The text also details a system of subject codes used to categorize the authors' areas of expertise, ranging from architecture and applied arts to philosophy, religion, and social sciences. Countries are noted where authors have spent significant periods of their careers. Language is mentioned if it's not immediately clear from context.
