The facts are compelling; twisting them only weakens one’s case.

the records of the copyright office, but I wish they had so
stated.

The number of registrations, of course, is not the same as the
number of works: A dozen songs registered as a “song book”
will be 12 songs promoted to the public domain once the
copyright expires. On the other hand, a compilation of
public domain stories registered as a “compilation” in
theory doesn’t take any of the individual stories out of the
public domain.

But while counting the number of registrations isn’t the same
as counting the number of works, I have no better method
to offer.

Qualitatively the shape of their no-extensions-since-1963
curve seems to lie between the predictions of my
constant authorship per year model:

and my constant authorship per capita per year model:
