The hazards of history research

I'm looking around on the internet for some sources on the "putting out" system that was common in early America. Stay with me. Putting out refers to the practice by which children, often orphans, would be placed in the home of a relative or friend to work. These children would be raised by their new families as if they were their own. All I wanted to do was find some books that talked about the putting out system. My dilemma? Google it. I dare you.
