Choosing subfloor for nailing hardwood on slab

I'm planning to install solid hardwood in the entire house. First floor is on a concrete slab. What do I select as a subfloor - OSB, 3/4 plywood, T&G plywood?

On another note - any book/guide to recommend for installing hardwood?

Roman, welcome to the forums! You will need to install a product like Advantech, which is a water resistant tongue and groove subflooring in 3/4" X 4' x8' panels. However, unless you install this subflooring on a "sleeper" system, you will not be able to drive the flooring staples to the proper depth, and you will have moisture problems. How high can you build up the floor to match the existing thresholds in the house, if any?
