Some books look so beautiful on the shelf. Not only for their aesthetic virtues, but for what their spines say about the owner. The four hardbound volumes of Donald Knuth’s “The Art of Computer Programming” — all snug in their dark purple case — send a clear message: Step aside, Muggles, because you’re in the presence of a Real Programmer. A Serious Practitioner of Computer Science.

Bill Gates once said, “If you think you’re a really good programmer… read Art of Computer Programming… You should definitely send me a résumé if you can read the whole thing.”
