I’m looking to change my reading and buying habits away from Amazon and need an alternate source for my ebooks. Where can I buy ebooks that won’t expire or have their licence revoked and will allow me to download a copy of that ebook I can store on my own system regardless of the websites status?
Baens library has been doing this for the past 25(?) years. They even have a free library. https://www.baen.com/catalog/category/view/s/free-library/id/2012
