Libraries have entered the 21st century. Download the Libby app, sign in with your library card, and you can "borrow" an ePub for 14 or 21 days. When the time expires, the file self-destructs. No late fees.
You are not a prisoner. If you buy an ePub book from Kobo or Google Books, you can read it on a Barnes & Noble Nook, an Apple iPad, an Android phone, or a PocketBook. You aren't forced to buy a specific brand of hardware to access your library.
Unlike the PDF (Portable Document Format), which is designed to lock the layout of a page (like a snapshot), ePub is . Think of ePub as a river of text rather than a frozen lake. When you change the font size on your eReader, the text "reflows" to fit the screen. This is the magic that makes reading on a 6-inch phone screen as comfortable as reading on a 13-inch tablet.
