It could work like this:

1. People go to the library, take some books home, and scan them in.
2. People who support the project donate some anonymous bitcoins.
3. The system automatically divides the bitcoins to each person taking part in the project each month. The more pages you upload, the bigger your share of the donations.
4. Continue until every book existing in the world is uploaded, for free, without any restrictions, in one amazing library for every person on the planet to access.
