If there is any book that you should get in paper form, it is TAoCP. This is one book where the author has taken great care, and decades of work, to truly build the book from the ground up. The book, the fonts, and the style were developed for paper. Knuth even has 5 other volumes of books containing the instructions and source code to reproduce almost every single curve, stroke, and space you see in the books. I think advocating digital publishing is probably good, but not for all things. Books shouldn't be treated as source code with continuous deployment. Even one word on one page can massively restructure the rest of the document, making it extremely difficult to coordinate and fix. What I think should be fixed is the dissemination of authentic books at a reasonable price, for especially students who typically don't have much money at all.
