@hawkeye10,
I can kind of see that, hawkeye, but believe it or not, not everyone has a computer and the schools don't have enough computers for every child to have one to use all day. This is true even in a fairly wealthy school like Mo's old school. Mo has friends that don't have computers at home.
The school has book drives/sales at least twice a year and they are always begging for books to be donated. Each teacher puts up a list of books they'd like to receive during the sale and there is always a donation box so people can buy books for other schools.
Books aren't going anywhere soon, especially children's picture books.
