Copyrights

It's copyrighted the minute you publish it. You can register the copyright with the Library of Congress; it's an easy process but it's by no means necessary from a legal standpoint.

Your primary concern should be writing something beautiful enough and innovative enough that people would want to steal it.

 

I will go one further:

 

Hi, DarkAngel.
People say that it's not necessary to formally copyright your works, but personally I want the library of congress to have a file on my project, that anyone can look up and verify. The address you want is here: https://eco.copyright.gov/eService_enu/start.swe?SWECmd=Start&SWEHo=eco.copyright.gov. Create an account, register your work, pay the fee, and in six months they'll send you a registration certificate. Relatively easy, and gives you ammo if anyone tries to rip off your work.

 

It's also required if you want to claim statutory damages or even sue according to the US code.
