The study presents data and commentary from 37 institutional digital repositories worldwide including but not limited to: Johns Hopkins University, the Association of European Research Libraries, Instituto de Salud Carlos III, OECD, Rutgers University, University College Dublin, Iowa State University, Heart of England NHS Foundation Trust, Oregon State University, the World Bank, the University of Seville, Qatar University, Montana State University, Utrecht University and the University of Canterbury, among others. The 150+ page study presents detailed data on budgets and spending, man hours devoted to the repository, revenue generation and fees, access policies & content viewing restrictions, levels of cooperation from faculty and parent institution staff, marketing, cataloging, downloads and other user statistics, ePublishing & peer review efforts, and much else of interest to library staff and suppliers interested in repositories, content distribution & publishing and open access. Just a few of the report's many findings are that: The digital repositories in the sample were operational for 5.18 years on average, with a maximum of 16 years. About 86% of repositories sampled do not charge users a fee in any form; none of those charging a fee were educational institutions. Level 1 or Level 2 Carnegie Class Research Universities in the sample (and their equivalents outside of the USA) had a mean of 1,104,140 downloads in the past year. For US-based repositories, 27% of downloads came from countries other than the US itself or Canada. In case of BA or MA Granting Institutions less than half (43%) of the repository downloads come outside the parent institution, while for other types of educational institutions at least 76% on average comes from outside the parent institution. Non-US repositories sampled experienced higher increases ($16,562 on average) in their repository budgets than their US counterparts ($5,006).
