Interesting point. The US entered the Berne convention on 1 March 1989.
Given that for the Berne convention the actual date of publication is
the starting point, I wonder whether K&R2 already did fall under it.
(At that time the Berne convention stated that a copyright is retained
until 50 years after the death of the original authors. Since that
time that has been increased to 70 years.) So the remaining questions are
1. Was it published before 1 March 1989?
2. Did the United States ratify the Berne convention only for works
published after 1 March 1989 (I think not)?
(Note: for the Berne convention the copyright notice is irrelevant, and
can be omitted. However, for works published in the US, it remains
relevant in order to be able to be awarded damages, according to US law.)

So you think that if somebody has made some money with his work that at
some point it is enough?
