Publisher and copyright holder are both different persons, a copy right holder is the author of a piece of art, literary works, drama, novels, story etc etc and a publisher is a person who or a publishing house who takes the copyright from the author or rights of the work and publishes it as a book or film etc etc.
You will know that the work has been copyrighted if it includes a copyright notice, which is marked either by a c in a circle (Â©) or the word copyright followed by the date of first publication and the name of the copyright owner. 1  If the work is a book, look for a copyright page. If the work is a CD or LP, look for a reference to the copyright on the packaging. 2  If the work is a magazine, the copyright will likely be found near the Table of Contents at the beginning of an issue.
