This book explains how information literacy (IL) is essential to the contemporary workplace and is fundamental to competent, ethical and evidence-based practice. In today's information-driven workplace, information professionals must know when research evidence or relevant legal, business, personal or other information is required, how to find it, how to critique it and how to integrate it into one's knowledge base. To fail to do so may result in defective and unethical practice which could have devastating consequences for clients or employers. There is an ethical requirement for information professionals to meet best practice standards to achieve the best outcome possible for the client. This demands highly focused and complex information searching, assessment and critiquing skills.
