Corinne A. Seeds University Elementary School, Managing Information in a Digital Age, 1996. Managing Information in a Digital Age presents the process and essential skills for embedding 
information literacy strategies across all areas of the elementary through high school curriculum. The curriculum—divided into seven areas: questioning, identifying and collecting, evaluating, sensemaking, reflecting and refining, using, and assessing—seeks to promote the skills, knowledge and attitudes that will help students to develop effective lifelong information awareness, seeking, management and presentation strategies.(Cathleen Galas, co-author)
