>>Pressumably the old URL was distributed over e-mail or something. I am not so much worried specifically about my own articles, but rather in general, that lots of articles are no longer available under the old addresses, which may be similarly distributed by e-mail. Of course, I don't have a reference for each and every article, but I do remember they used to be accesible under addresses similar to the one I gave you, including the edition and a page number, and (for the Spanish edition) with "/spanish/" in between.

I don't know. A Web search ("web pages that link to this page")didn't reveal a single hit; I assume it was passed along by e-mail.

Does this mean the URL can change from one day to another? - I suppose yes.

Well, I guess I will just have to tell friends to search by edition, by article, etc.
