EPUB is an open standard for electronic books, or eBooks. The EPUB eBook was developed to be an international standard for electronic books. Through our OverDrive collection, GCPL offers EPUB eBooks because of their compatibility with a growing number of eReading devices. From our OverDrive Help page:
An Adobe EPUB eBook is a digital version of a print book that has been optimized for on-screen reading. The text in an EPUB eBook is reflowable, which means that you can change the font, resize the text, or alter the size of your display, and the text will rewrap itself to fit the available viewing area. Adobe EPUB eBooks also support embedded content, allowing, for instance, a Flash video to be embedded within an eBook.
