Only one on there that I’ve read is “Moby Dick” so that’s all that I can offer any help on. I don’t know how far into it you are, but it can be a toughie at times, especially when Melville goes off about how to cut p and prepare a whale after catching it. While it’s involved in the text, it isn’t necessary information by any stretch. Still, it is for the most part a very interesting read, and, of course, a classic, so go for it and good luck!
