It is not a case of "one size fits all," but patterns are beginning to emerge from empirical research into the subject. The length of the text seems to be the most critical factor. If the text is long, needs to be read carefully and perhaps involves making notes, then studies show that many people, including young people such as students, still often prefer a printed book, even if it is available as both an e-book and in electronic formats with options for making notes, enabling the user to search for and highlight the text digitally. This is not the case when it comes to shorter texts.
