If you are linking to someone's email address, you should ask their
permission first. Simple courtesy. Stale links are a problem whether the
link is automatic via HTML hypertext or manual via references, citations, or
whatever. Our library consultant tells me that only about 10% of her book
requests generated via references, citations, etc., etc. are directly
satisfiable; books go out of print, are "in print" but out of stock while
the publisher waits for enough orders before ordering an additional printing
(or the book is out of stock but listed as in print while the publisher
hasn't decided whether to actually print more copies), etc. If the author
of a document wants to link to another document, checks that the link was in
operation while they write their document, and checks that the link is not
likely to go stale i.e. there is no notice in the linked document or its
containing local web that this is just a temporary web, the author has done
as much as they can. Civilizations rise and fall, businesses go bust
(personal victim of two failed startups :)), suns go nova; the universe is
dynamic, not static.
>* What is the copyright status of text and graphics on the web?
Depends on what the publisher wants it to be. My assumption is that a
document is copyrighted with no general right to tweak the document unless
otherwise explicitly stated.
>I suppose the polite thing to do is to send email and just ask.
Nice to see an instance where common courtesy and the law agree...

This is a whole 'nother can'o'worms, wandering into the field of
high-security applications (mandatory access controls/B-level security). I
have a hunch that the Web is just not suited for this kind of access, due to
the stateless nature of HTTP as well as the various other security
considerations you would probably want to implement at the same time you are
protecting your Web addresses. Security gurus: any comments?

I hope that this will be implemented as a client-side option. There are
people who would not care for themselves to ever be exposed to it, while
others would want to block access for their children up until a certain age.
>* Does a web document act like a newspaper or a magazine w.r.t. lible
Since the public part of the Web is intended as a mass medium, I would say
so, with perhaps some modifications for the fact that the user has to make a
conscious decision to follow a link, whereas watching TV is fairly passive
and reading a magazine or newspaper is less so.
