I don't know that it's much of a positive tho, basically going from active to passive learning. Sitting through videos instead of reading books (much more efficient too IMO) seems like a prime example of attention span erosion to me.
Well, local libraries don't really have that much in the way of good academic texts - you have to have access to a university library, or be willing to fork over $60 of your own for a print copy, for that. But I get what you mean.
