The footnotes are not renumbered between chapters but just continue on. I’ve been thinking about this because I noticed this is exactly what happens in Richard Rhodes’s Dark Sun. Wouldn’t it be easier to just to number them incrementally throughout the whole book? 1

That means in order to uniquely identify a footnote you need to know the chapter and the note number. Why are footnotes generally composed of compound keys instead of being primary keys themselves? I’ve noticed that in most books I read that contain footnotes, the footnote renumbering restarts with each chapter.
