pruning cherry trees or fruit trees in general

Can anyone point me to some good links/info on pruning cherry trees and/or plum trees? I planted some this spring. My husband found a site about cherry trees, but didn't bookmark it.

 

Here is a link to the U. of N. Carolina horticultural department. The explanations are very clear, and diagrams are included. I downloaded this when we first started our little orchard, and have used it as a guide for pruning and training our trees. So far, so good!

Thank you!
