As I remember, until the 70's the copyright was for 28 yrs, renewable
once - but I do remember seeing something that many yrs ago it was
14 years.

Yes, but at that time it was also renewable [for a total of 28].

It is widely known that "The C Programming Language" expires in January
2038. :)

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?

In the United States, the Constitution requires that copyright be
for a limited time, so this is axiomatically true here.

That's the constitutional basis for copyright, yeah. At what point do
longer copyright terms gain less in incentive to produce more works than
they cost in discouragement of production of derived works?

In the Berne convention that is not the basis for copyright. And even
after the copyright has expired it may be possible in many countries that
it is not allowed to produce a derived work (although reproduction of the
original work is now free), even not by the original copyright holder if
that is not the original creator. This is known in German as "Urheberrecht",
and applies particularly to works of science and art. But what *are*
derived works of things that fall under "copyright"? A pastiche of a
well known work is certainly a derived work and also permitted under the
copyright law. There are quite a few of such available, derived from the
Harry Potter books.
