<<But anyone can go to a library and make a photo-copy for their
own use
(fair use).>>
I'm a bit late (holidays), but that's not actually always the case,
Frank.
Some libraries don't allow photocopying of papers on the grounds, I
suppose,
of possible infringement of copryright. Whatever the reason might
actually
be, not all allow it. Out of the kindness of their heart, a
student tried
to photocopy a paper from their university library for me. Their
straightforward request was met with shocked eyebrows and a shaking
head
from the librarian, even after the addition of a pretty please.
They were
sent to the corner of the room and instructed to take notes.
Ever so kindly, they did just that and sent those instead.
