Educational Technology and Copyright Law

In this article I learned that copyright is the "work of authorship". That is the United States federal law that protects original writing of someone. Also, i learned that everything is copyrighted as soon as you write it. You do not need to fill out any paperwork or anything. As soon as you copyright the thing you drew or wrote you have these 4 rights:

1. Reproduce your copyright work
2. Display your copyright work publicly
3. Prepare derivative works based on the copyrighted work
4. Distribute copies of copyright work to the public by sale
