This paper presents a summary of the entire body of research, 2008 to 2022, from Project Information Literacy (PIL) on the strategies students use for finding, using, and creating information for college courses, in everyday life, and the workplace while navigating a vast, ever-changing information landscape. Major findings from 12 reports and seven related research articles are presented. A computational analysis of 2,475 citations from 1,961 sources provides empirical data for interactive information visualizations about the geographic reach and impact of PIL's research on the wider educational context. This retrospective, the final publication produced as part of more than a decade of studying college students, concludes with a discussion of PIL's practical impact on information literacy instruction and suggestions for future research.
