Linking to yourself

I've seen a few sites do this.

They write an article (eg http://www.mydomain.com/article.htm) and within the article, they link back to themselves (eg http://www.mydomain.com/article.htm)

What would be the advantage of linking back to yourself from within the same article?

 

they could be doing it so it's easier to refer people or to help stop people just copy and pasting there article, not sure.

 

Protect his article.
I think too.

 

Yes you can paste you article link or another article link related to that content in your post , so anyone newbie copy it and paste it in his blog we can catch him by this method .

 

I do it to make it easier for my readers to find the info I'm referring to

 

I also do it so readers can find things easier if I'm referring to it specifically
