It would be interesting to see if these results replicated when the target was "home encyclopedia set" or "university library" Probably not possible these days since it would be hard to test when people already have internet access l, and part of that access can include these things. But I suspect this phenomenon is not unique to the internet, and would be more generalizable to any readily available source of information. Though the effect would probably increase with ease of access, so the internet would produce a larger effect. I acknowledge this is just speculation though.
