I understood that there is an exemption in US law just for libraries ( https://copycense.com/2012/03/05/section-108-fair-use-are-not-mutually-exclusive/amp/ https://copycense.com/2012/03/05/section-108-fair-use-are-no... ), but it wasn’t clear whether Google was covered when acting as an agent for the libraries. But it seems to be the reason to require the rigamarole with library cards.
