In 2011, Kim investigated the perceptions of faculty members from 17 Carnegie doctorategranting
universities in the US regarding IRs. He reports that about 60 percent were unaware
of their university IRs and explored factors that encourage faculty participation in IRs as well as factors that hinder faculty contributions to IRs. Of three statistically significant barriers

concern, though time and effort were also seen as obstacles. Kim concludes by underlining
the importance of strengthening digital preservation and copyright management in IRs to
increase faculty participation
