Literacy is typically described as the ability to read and write. It is a concept claimed and defined by a range of different theoretical fields. The United Nations Educational, Scientific and Cultural Organization (UNESCO) provides a useful and reasonably non-controversial definition of literacy--albeit one that emphasizes print texts (and doesn't include images, video, etc.); for UNESCO, literacy is the ability to identify, understand, interpret, create, communicate, compute and use printed and written materials associated with varying contexts. Literacy involves a continuum of learning in enabling individuals to achieve their goals, to develop their knowledge and potential, and to participate fully in their community and wider society.
