Did you catch the library related question in this week’s The Ethicist column?
Through my public library, I can check out a book on my Kindle for 21 days. Then the system sends a signal to erase the book and make it available for someone else. But there’s a loophole: if my Kindle is offline, the book isn’t deleted and is still available for another reader. So if I need another day, I leave the Kindle offline and continue until I’m done. When I go back online, the book is deleted. I say that’s fine. But my co-worker says that I promised to return it after 21 days — just like a physical book — and I must honor that promise.
