Verified answer

tiny, several points. One, your book is copyrighted the moment you save it to a fixed medium, like paper or your hard drive. You do not need to register that copyright for it to exist.

Two, never copyright a book manuscript before submitting it, since revision and editing will probably be required. The book you copyrighted won't be the one that goes to press--and publishers rightly regard an author who copyrights before submission as both a paranoid with delusions of grandeur and someone who believes the publisher might steal--not the impression you want them to have of you.

Three, you don't need an attorney to register a copyright. It can be done online or by mail easily.

And four, was there a question in there someplace?

Wonderful! What's the question?
