Container Gardening

Hi everybody,
I'm seeking books and websites focused on growing fruit trees in containers. Can anybody recommend some?
Also, can anyone recommend any online sellers of dwarf fruit trees?
Thanks!

Meyer lemon, Fig are two that popped into my mind that can be grown in containers.

Here's some websites to search for trees/bushes

"Fedco seeds", "Norse Farms", 'Miller Nurseries", "Elmore Root Nursery", "St Lawrence Nurseries", "Henry Leuthard Nurseries", "Stark Bor's Nurseries", and "Nolan River Nut Tree Nursery".
