They’re great books, beautifully typeset, but they’re not for everyone. Meant for people who appreciate math, they go pretty hard. Personally I’ve owned the first three volumes for 20 years now and I still learn something new every time I open them. It will take me another 20 years to work through Volume 4A and 4B. While I can’t say that anything in there has been directly relevant to my work, they’re just fun to read.
