There is an anachronism were the following circumstances collide:
- lending is limited to the original bought copies (a library cannot create more copies of a book for further lending)
- digital lending requires sending the data to another device creating a copy
- digital lending has near-zero marginal cost (specially at scale)
- digital borrowing has near-zero marginal cost (no library membership, single click borrowing for some minutes or some hours with single click return)
IMHO I think Archive is legally in the right and it is only due to the previous circumstances, Archive.org collaborating with _a lot_ of libraries, and the tension between the older/traditional socialist/communal lending practice vs newer/contemporary private property laws that allows this conflict to emerge.
