How does copyright work?

The law says that only the creator of a work, or his heirs, and no one else, has the right to make copies of it. Thus “copyright.”

The creator can lease out that right, give it away, whatever, but it’s his.

All the complications (and there are many) result from deciding who the creator is, what constitutes a copy, and how long copyright should last. Especially what constitutes a copy.

As for how it works in practice, copyright infringement — that is, making a copy without the creator’s permission — is a civil offense, not a criminal one. (What you do with the copies may well be criminal, though, since they’re stolen property.) That means that you won’t be arrested for copyright infringement, but you can be sued, and if you lose the suit you will be ordered to pay the creator everything you made off the infringement, plus any damages the creator can show to his own use of the property, plus (if the copyright was registered) punitive (punishment) damages.
