A:Answer Hello! While you cant add memory to this Kindle, rest assured it will hold thousands of books. Here are some other options for you: Kindle Unlimited is a service that allows you to read as much as you want, choosing from over 3 million titles, thousands of audiobooks, and magazine subscriptions. Explore new authors, books, and genres from mysteries and romance to sci-fi and more. You can read on any device. The Kindle is compatible with a number of different eBook formats and does work with a number of different library book services such as Libby. In most cases, you will be able to take out the digital copy of a book using your library's eBook service and then there would be a "Send to Kindle" option for it. At that point you would be able to send it to your Kindle for the allotted time that you have it taken out for. Your best course of action to take to ensure that your library offers that service is to consult your local library's librarian. They would be best able to tell you what you would need to do and if they have that service available. Thanks so much for your question, and I hope you have a great day!
