The 21 st Century Information Fluency Project (21CIF) began in 2001 when the Illinois Mathematics and Science Academy received funds from the US Department of Education to research and develop training in the largely unexplored field of online information literacy. It immediately became clear that the largest needs in this area were for professional development and resources to help educators and students improve their ability to locate, evaluate and use digital information more effectively, efficiently and ethically. That has always been, and remains today, the mission of 21CIF.
