How do I secure a copyright?
Copyright is secured automatically when the work is created and fixed in a copy or phonorecord for the first time. Once an author has created material in a fixed form, she or he holds the copyright. No publication or registration or other action in the Copyright Office is required to secure copyright.
However, registering the copyright helps to establish a record that you are the author, and helps to establish the date when you claim to have recreated the material.
So, what does copyright registration mean, then?
In general, copyright registration (with the Copyright Office in Washington D.C.) is a legal formality intended to make a public record of the basic facts of a particular copyright.
