By default, with either the standard LaTeX classes or the KOMA-script classes, empty pages (such as may occur using
\cleardoublepage) have no page numbers.
Why is this? In my — unprofessional — opinion, every page should have a page number. When I want to go to a particular page in a book, having page numbers oo every page assists me in finding the page I need, and page numbers do not only serve as an anchor for content.
However, I am by no means a book designer, and perhaps the default setting is one that I should not want to override. What is the reason for the absense of page numbers on empty pages? Am I wrong with my reasoning above, or are scholarly opinions about it divided as well?
