In this paper the author compares the use of digital materials that have been deposited in The Ohio State University (OSU) Knowledge Bank (KB). Comparisons are made for content considered in scope of the university archives and those considered out of scope, for materials originating from different campus sources, and for different types of content. Results show that both mediated and unmediated content is used and therefore justifies the preservation costs for unmediated content. Results also show articles and undergraduate theses are most frequently used type of materials leading to the conclusion that it is important to collect content from all levels of the educational process.
