Hey Scarlet,

When you write something, it's copyrighted by default, however, registering the work gives you the proof you need in case you ever go to court.

You can also do what's called a "poor man's copyright" where you send the document to yourself in a well sealed package and through registered (not certified) mail. Then, if you ever go to court, you can move it and it's postal record including the date into evidence and prove that you created the work on or before the date it was mailed. Then, after the case, you have a court record.

I've done this myself with some inventions I made but I've never had to go to court yet.

If you want to "register" the copyright with the gov't, just call the gov't printing office and order a copyright information package and it should contain all the forms and instructions you need to proceed.

Let me know how it goes.
