Gayle, I have heard the same. Now, I’m not sure if they make exceptions for sites that are reprinting with permission and posting a notice to that effect. There may also be some allowances for snippets used in curated content, or for content duplicated on archival sites like the Wayback Machine. But in general, unique content is important.

I don’t add copyright notices here at LiteracyBase because I just didn’t think to do it. The content I have published so far is not extensive and informative like your posts. In other words, I don’t think it’s good enough for somebody to want to steal it. But I suppose no matter what you write, you should just develop the habit of adding a copyright notice. Some writing sites are nice enough to add it for you! It’s incorporated into their writing module. 🙂

Copyrights save the writers’ creative works on the internet all over the world but I have seen people cheat and shuffling it write a new article for any site but is wrong for self and such person self creative powers. It is against the natural law.

What is Copyright?
Copyright is a form of protection provided by the laws of the United States (title 17, U.S. Code) to the authors of “original works of authorship” including literary, dramatic, musical, artistic, architectural and certain other intellectual works.
***This protection is available to both published and unpublished works.

Material in the “public domain” is intellectual property that does not come under copyright laws.
Nearly all work before the 20th C. is not copyrighted.

What is Plagiarism?
Plagiarism is the the act of stealing and passing off the ideas, words, or other intellectual property produced by another as one’s own. For example, using someone else’s words in a research paper without citing the source, is an act of plagiarism.

History of copyright:

First law enacted 1790.
1976 copyright law followed international law, extending copyright for 50 years after death of the author/creator.
On October 27, 1998, President Clinton signed into law the “Sonny Bono Copyright Extension Act,” which extends the terms of almost all existing copyrights by 20 years, to provide copyrights in the United States the same protection afforded in Europe.

The basic term of copyright protection, the life of the creator plus 50 years, has been increased to life plus 70 years. The term for “work for hire” has been extended from 75 to 95 years.
