What my library said via email about the Economist when I asked.
“Libby lost The Economist to a competing product called PressReader. We have that service too. Unfortunately, PressReader didn't add the magazine to the package we are already paying for. We would have had to pay for The Economist separately, and they asked an exorbitant amount. We decided not to add it at that price. Sorry.
“It's frustrating, but the options for library access to online content are very limited. Providers can charge crazy rates, and libraries have to suck it up and pay it, or say no because there's nowhere else to go.”
NOTE: university libraries have the Economist, but if you are not a student, with a university email, you’re out of luck.
