copyrights now app? and other copyright questions.....

[MOO]

Has anyone ever heard of the Copyrights now app? If so, would you recommend it? It's supposed to make it possible to get your copyright in three easy steps and save you money. It's offered through Bowker.

Another question I have is, if you have a book that includes a page with music notation (sheet music?) would they need to be copyrighted separately?

Also, if I were to copyright a collection of sheet music, could I then use them in books separately? I was thinking it might save me money in the long run. I plan on illustrating some other lullabyes. Thanks!
