Hi Alll

Just to add to Angie's email, the magazine Web Techniques
(www.webtehniques.com) had a useful article on Copyright and how it applied
to databases.

Have a look at http://www.webtechniques.com/archives/1998/01/just/

> An individual or group of individuals does NOT have to put the

> There are exceptions for people employed by another to create

> Of course defending your copyright in court is easier if you've made
> it clear that it is yours. That's why people do it.
> If you're trying to extract sections of a directory like Yahoo it
> becomes really grey as technically they own the listing but they
> don't own the sites listed so it's a toughie.
> Contact the website owner and see if they are happy to let you use
> their content. It helps to put links back to the original site as a
> courtesy. But unless you've got the site owners permission you're
> probably breaking copyright somewhere.
> Just using their table layout with the results could be close to
> crossing the line. A designer has copyright on a site too :-)
> Important note:
> Information being public does not mean that that info is in the
> public domain. not in respect to copyright law anyway.
> Example:
> You read a synopsis of a book on the web, this doesn't mean the
> author let go of his copyright or moral rights to show the world the
> synopsis.
> If anything this is the point of copyright, so a person can
> publish/create a work without everyone else being able to claim it's
> theirs the second they read it, it's for your protection as well as
> the big corporations.
> Copyright is a mine field which is why lawyers make so much money try
> to protect someone's copyright, it's not clean cut sadly.
> If you didn't write it, ask the person who did. If you have an email
> from them saying you may use it then you're clear.
> I do know a few search engines let you use their content. generally
> you either pay for it or link to one of their pages so their banners
> are still there etc.
> Of course there's nothing to stop you using their directory to
> compile your list of links. However if you're actually calling a file
> off of their server you are directly using their content
> definitely ask them.
