This book provides a comprehensive, easy-to-understand introductory guide to information, offering students the critical tools they need to shift their positioning from consumers and users to creators and critics. Searching, accessing, and using information are central to most daily lives. Yet, many users are not able to define what information is, identify who controls information, and create information to achieve a common good. In this book, Micky Lee teaches readers to critically interrogate key issues such as the categorization of information and knowledge throughout history, what digital divides are, why information is gender and race biased, how governments and corporations control citizens and consumers, as well as how we can resist unbalanced power relations. Readers will not only be able to relate these issues to "old" technologies, such as writing and printing, but will also be able to examine futurist technologies through the lenses of these enduring issues. A thoughtful and comprehensive overview, this is an ideal book for students and scholars of media studies, information and society, and communication and technology.
