I can give general advice, but consult your attorney about your country's specific copyright laws. By US law, an article is protected by copyright when it is published, whether or not you list copyright information. You can register your documents with the Library of Congress, though few do this for websites. The following statement should be adequate for most purposes: ""Copyright © 2000, by John B. Doe. All rights reserved."" The primary purpose of your copyright statement is to put readers on notice that this is your property. Since websites are so easy to copy, I usually go further and say, ""Text, graphics, and HTML code are protected by US and International Copyright Laws, and may not be copied, reprinted, published, translated, hosted, or otherwise distributed by any means without explicit permission."" It's difficult to enforce your copyright in court -- the legal costs would be excessive. However, it's usually sufficient to send violators a stiff note demanding that they remove your copyrighted documents from their site immediately. If they don't, contact their web hosting service. For a hosting service to knowingly host stolen materials saddles them with legal liability. Few are willing to risk it, so they usually force their subscribers to remove the offending materials immediately.
