Since many people do not really understand what a copyright notice means, many copyright owners include various types of warning or explanatory statements near the copyright notice. The purpose is to make clear to users that the work is copyrighted and may not be reproduced without the copyright owner's permission. It does not cost anything to place this type of statement near the copyright notice, and it may help deter copyright infringement. But remember, such statements do not take the place of a valid copyright notice.
Here are some examples of warning statements you can use near a copyright notice on a website:
No part of this work may be reproduced in whole or in part in any manner without the permission of the copyright owner.
No part of the materials available through the [DOMAIN NAME] site may be copied, photocopied, reproduced, translated or reduced to any electronic medium or machine-readable form, in whole or in part, without prior written consent of [COPYRIGHT OWNER’S NAME]. Any other reproduction in any form without the permission of [COPYRIGHT OWNER’S NAME] is prohibited. All materials contained on this site are protected by United States copyright law and may not be reproduced, distributed, transmitted, displayed, published or broadcast without the prior written permission of [COPYRIGHT OWNER’S NAME].
On the other hand, some website owners are happy to permit certain types of unauthorized copying, while prohibiting others. To make it clear to web users what types of copying are permissible, you can include a statement like the following along with the copyright notice:
The materials on this website may be copied online, but may not be reproduced in print or any other media without written permission.
The materials on this website materials may be copied for noncommercial personal use only.
The materials on this website may be freely copied and distributed so long as our copyright notice and Website address is included.
