Can I copy copyrighted articles?

Creating new web site

[exposo]

Hey everybody,
I've been surfing for hours searching new content for my web site and I found site were there were cool articles about the theme of my site. Those articles were written in one book of an author. So at the end of each article such phrase is written:

"Copyright © 1987 by Author XXX. The Copyright has been reserved in all forms and it may not be distributed. It is partly presented with the express permission of the author. Any reproduction in whole or part by and individuals or organizations will be held liable for copyright infringement to the full extent of the law. "

Can I copy his articles to my site?
Can I change parts of his text?
What should I do to copy his articles to my site, to be everything legal?

Thx. and have a nice day:)

>>I find it interesting that you chose two examples of fiction that are in the public domain.

Believe it or not, that was just by chance. I had no clue that those works were in the PD.
