A nonprint source is a reference material that is not in written form. However, a nonprint source, such as the Internet, may include print information.
Nonprint sources include images, films, television broadcasts, radio productions and music recordings. One of the most effective methods of dealing with nonprint sources is by asking questions, according to Frank Baker, who is a media consultant for the South Carolina State Department State of Education English Language Arts team. By classifying information according to the category it belongs, critical thinking and critical viewing are enhanced. These skills are essential elements in what is known as "media literacy."
