Digital publishing includes the digital publication of e-books, digital magazines, and the development of digital libraries and catalogues. It also includes an editorial aspect, that consists of editing books, journals or magazines that are mostly destined to be read on a screen (computer, e-reader, tablet, smartphone).
Amazon.com’s E-reader, Kindle, and their self- publishing platform, Kindle Direct Publishing, are part of digital publishing. People create games and apps and have them published in the Google Play Store. Musicians record their music into MP3 files and upload them to iTunes which will digitally publish their music and make it available to iPods, iPhones, and other players.
When you listen to Pandora, Spotify, or any other online music service, you take advantage of their distribution network which is a form of digital publishing. When you look at digital images created in Adobe Illustrator or Adobe Photoshop, you see artwork that has been digitally published.
