Totally agree with the first part.
> Controlled digital lending had a chance of getting off the ground. The IA's Emergency Library's unlimited digital lending burned it to the ground and stomped on the ashes.
One of the problems libraries face is that many publishers will not sell them "real" licenses, but only "quota licenses" that allow a total of n borrows and m concurrent borrows. Once the total number of borrows is exceeded, the license expires. n can be very low.
This was not always the case. 10 years ago, most licenses were unrestricted licenses that allowed an unlimited number of total borrows, but only limited the number of m concurrent borrows at a time - just like it would be if the library bought m real books.
The argument is that real books wear out - digital books don't. However, my local librarian vehemently disagrees with this statement, as many books survive more than 100 borrows, something the new e-book licenses will never manage.
Additionally, those "quota" licenses are still way more expensive than an equal amount of m real, physical books. It's insanity. My local library could, by their own account, not survive if the number of digital lends permanently increased significantly (like it did in 2020).
So if controlled digital lending had a chance for the mainstream, the publishers killed it many years ago, when many of them decided to just not sell libraries unrestricted licenses anymore, but only "quota" licenses. :/
