Same for me. My handwriting is atrocious. Beyond that I'm not sure what I can add in the form of marginalia that hasn't already been proffered in greater detail on some website that is a mere Google search away. But if that's what Hubski wants that's what Hubski is gonna get. Don't say I didn't warn you. p.s. I am exited though. This is going to be fun.I'll leave some of my own, but my handwriting is awful and I'm afraid of marring pages with it to be honest.
I will say for one that I turn to books often when no other option is present - for instance, when I have no Wifi or data signal. I had to travel a lot via train for work this summer and the wifi never worked, and I read a lot then. So sometimes, Google and so on aren't available to look up "hey is this a reference" or so on, and by the time one has returned to the modern world the moment has been lost and the reading has gone on (the narrative, so engrossing!) and the question hangs forever. Or at least for a long time until one gets bored and decides to look up the book on Wikipedia, or what-have-you. Also, it can be fun to do the analysis oneself :)
