I'm looking for references on paratext (specifically about foot/endnotes and commentary, how does one decide when they're needed and what kind of information should go in them) but I'm struggling to figure out how to search for it. My school's library is currently on strike so I can't go look through the shelves (yes this is a thing I actually do, stop judging me) and it doesn't seem to have a list of the books in their collections, either. So I need keywords. ;_;
