If you find this sort of thing interesting, you may enjoy A=B by Marko Petkovsek, Herbert Wilf, and Doron Zeilberger. (Wilf was mentioned in the article.)
It's available for download at http://www.math.upenn.edu/~wilf/AeqB.html
I would like to add that Doron Zeilberger's opinions page is very interesting: http://www.math.rutgers.edu/~zeilberg/OPINIONS.html
Link seems to be down, but I'd be interested.
If you're still having trouble accessing it, here are direct links to the mirrors:
