[diffeomorphism]

The article does not mention ebooks, which is a surprising omission considering it involves Amazon.

I don't know how it is in the US, but for instance German libraries offer to loan ebooks: http://www.onleihe.net/

Donating ereaders and rights to ebooks to libraries seems more effective than printed books.

Big caveats here are Amazon's monopoly position, DRM and copyright and loans for ebooks vs. physical books.

Yes, ebooks are important and English law changed recently to make it easier, although libraries are still limited by licensing terms: http://www.legislation.gov.uk/ukpga/2017/30/part/4/enacted
