So! Publishers don& #39;t buy rights to a book. They license those rights (albeit usually for the life of copyright, but contracts should always have a way for the license to expire if the work is out of print, and US copyright law allows for expiration even if it& #39;s in print). 1/4

Which is why when you "buy" an ebook, you& #39;re not actually buying it. You& #39;re licensing access it to it. And if a publisher& #39;s license went wrong in some way (like if they never actually had the ebook license, it happens), then they have to revoke that access to all accounts. 2/4

So if you keep your ebooks solely on the device/app where you "bought" them, it& #39;s like storing your physical books in the shop where you found them, and someday you might come to that shop and find they removed the book. 3/4

I doubt anyone much cares or will/can treat their ebooks differently because of this, but it& #39;s just a reality that was spinning in my head today, so I& #39;m spinning it your way, do with it what you will. 4/4
