The Digital Millennium Copyright Act (DMCA) protects search and internet providers  from lawsuits concerning copyright infringement by third parties.  However it also obliges them to investigate and respond to complaints by authors about alleged copyright infringements under the threat of the loss of their own protection.  If the complaints are valid, the search provider must block all search results to the offending web pages, and this may extend to the entire offending website.  Complaints to search providers such as Google, Bing and Yahoo are particularly effective with overseas websites where American and European copyright law may not provide effective copyright protection.  Complaints to ISPs and blog hosting companies, especially in the US and Europe will often result in the complete removal of offending websites or blogs.  I do, in fact, lodge these complaints when offenders that I find do not respond to my queries.

How do I find out when my work has been plagiarized?

Simple!  Anyone can do it.  Just select any phrase in my website of at least a dozen words.  Enclose the phrase in quotation marks, and copy it into a Google search box.  Then press the Google Search button, and Google will return all the occurrences of that phrase in any website on the net.  Just click on the search results and see if the page actually contains more of my copyrighted content.

Alternatively, anyone can purchase web searches for copyright violations for their website from a great service called Copyscape.

What is a copyright?

The concept of copyright protection was set fourth in the original US constitution and affords the author of an original work specific rights that the author can give or sell to others or keep for him/herself.  It protects original intellectual material once it has been written down.   Note that the copyright extends from the time the work is committed to paper (or, more recently, to electronic media).  The work does not have to be published to be copyrighted.  Nor does it even have to be registered with the copyright office at the US library of congress.  This website began in the summer of 2000, and those portions which existed at that time were, and still are copyright protected, provided I can prove that I was the author at that time.

This website has been operating since 7/24/2000.  I can prove authorship of my website from November of 2001 by using a web service called the Wayback Machine which uses web crawlers to find and archive web pages.

I can also prove my authorship as a result of copies of my web site held by the library of congress copyright office, Certificate of Registration, TXu 1-571-382.

A copyright is good for the life of the author of the work, plus 70 years.

After filing so many DMCA complaints, I thought it might be appropriate to create an entire page explaining just how to go about taking down web pages that have infringed YOUR material. Click this link to find out exactly how to remove your work from websites not authorized to use it!
