the lovely and said:
No doubt? It is as if the public library lent books by having people come
into my home and take mine.
Well, no. It isn't like that at all. I gather you don't have a problem
with the end users seeing the material. If you did, you wouldn't place the
material in an unprotected directory on the World Wide Web.
So it is like you put up broadside, but you want to be the only one pointing
at it. It is not the copyright of the material you are complaining about.
It is that you imagine there is some kind of copyright on the address.
There is, of course, a technical solution to your problem. You could test
the http-referrer, and redirect offsite queries to a "Please access this
page through my site" thing. Whether it is worth irking the end users is up
to you. Moreover, Google and similar repudible services, will honor noindex
meta tags.
