When accessing or downloading EBSCO eBooks, you may see the choice to select eBooks in either PDF or EPUB format.
EPUB is an open eBook standard and file format that is optimized for viewing on devices. It automatically resizes to fit your screen and when you adjust font size. EPUB is the recommended format for download and is compatible with many eReaders and reading apps, including the iPad/iPhone, Kindle Fire, Galaxy tablets, the EBSCO eBooks app, as well as the Bluefire app for iOS and Android devices.
PDFs are not re-flowable, so their text size cannot be adjusted for display on various devices.
