Publishing means different things to different people. With the development of the Gutenberg printing press in the middle of the 15th century, oral traditions, as well as texts written by hand and recited aloud by literate elites were replaced by mass publications allowing large numbers of ordinary people to read on their own, but also requiring them to make their own sense of what they read. Nowadays, consumers of electronic publishing face a similar opportunity and challenge as technological advances take them beyond decoding and synthesis of information from printed text. They are required to interact with and evaluate multimedia materials, while understanding, as book readers before them had to, the innuendo, the context of ideas, the larger picture. Even more is expected from the audience of electronic learning (e-Learning), namely the acquisition of knowledge and skills through the engagement with electronically published material.
