Well I saw only had 2/3, here 3, Copyright,

Copyrighting is not something you can do to something,
It is a right that is automatically attributed to the author of a work.

There is a lot of misunderstanding about this, since in the U.S. it  
has only been that way since 1989, when they became party to the Berne  
Convention, which most of the rest of the world had been since the  
early 20th century.

That is why, only in the U.S., you had to register for copyright, and  
copyright notices had legal value.

But if I publish a book, I do not have to say (c) me, because it  
automatically is the case.

At the same time, because copyrighting is a right granted to the  
author of something, you can’t just go and copyright things made by  

You are granted copyright when you use work of others to make  
something which displays originality (though that is a sketchy concept)
