It is a sad tragedy that this article is not freely available on the web (at least as I can find).

Come on, $39.95 / €34.95 / £29.95 isn't much and I am sure Springer deserve to cash in on Knuth's work.

I can't tell if you're serious but...I can get it for free if I just wait to be in the office tomorrow (we subscribe to springer). If I remember that is.

However, many people here are not going to pay the money or have access through their employer, and will miss out. Free Knuth!
