I still don’t think that is true, because it assumes people that used the IA library would have used anything else (something that’s not their local library which is also free), and I just don’t think that is true.

I didn’t suddenly stop buying books on amazon when I could get them from the IA, the people who used it were the ones that could afford those books from Amazon in the first place.

Of course, me ‘thinking’ something is no guarantee, but I don’t have the numbers to say one way or another.
