This book explains how and why information literacy can help to foster critical thinking and discerning attitudes, enabling citizens to play an informed role in society and its democratic processes. In early 21st century societies, individuals and organisations are deluged with information, particularly online information. Much of this is useful, valuable or enriching. But a lot of it is of dubious quality and provenance, if not downright dangerous. Misinformation forms part of the mix. The ability to get the most out of the information flow, finding, interpreting and using it, and particularly developing a critical mindset towards it, requires skills, know-how, judgement and confidence - such is the premise of information literacy.
