What does it mean to be an ethical businessperson, and how does an ethical businessperson create, locate, organize, and evaluate business information? Critical business information literacy (CBIL) is the application of social justice to business information literacy. This article seeks to define, discuss, and realize CBIL by tracing the literatures of critical librarianship, critical management, and corporate social responsibility. To establish best practices, the authors drew upon applications of CBIL at four institutions of different size, geography, and scale. The intent is to provide spaces and foundations for further CBIL application and discussion.
