Academic librarians are exploring critical information literacy (CIL) in ever increasing numbers. While a smattering of journal articles and a small number of books have been published on the topic, the conversation around CIL has mostly taken place online, at conferences, in individual libraries, and in personal dialogues. This book explores that conversation and provides a snapshot of the current state of CIL as it is enacted and understood by academic librarians. It introduces the ideas and concepts behind CIL and helps librarians make more informed decisions about how to design, teach, and implement programs. It also informs library science scholars and policy makers in terms of knowing how CIL is being taught and supported at the institutional level.
