It depends! EBook digital licenses and access lengths vary by publisher and book. Many eBooks are rentals that include digital subscription access that is valid for a set time period (Ex: 180 days, 2 years) or for the duration of your course (Ex: Canvas eBooks). Other eBooks include lifetime or “perpetual” access that doesn’t expire, which allows you to own and access your eBook indefinitely. We recommend always checking the subscription length prior to purchasing your eBook to make sure you choose the option that’s best for you!
