The study presents data from 56 institutional digital repositories from eleven countries, including the USA, Canada, Australia, Germany, South Africa, India, Turkey and other countries. The 121-page study presents more than 200 tables of data and commentary and is based on data from higher education libraries and other institutions involved in institutional digital repository development. In more than 300 tables and associated commentary the report describes norms and benchmarks for budgets, software use, manpower needs and deployment, financing, usage, marketing and other facets of the management of international digital repositories. The report helps to answer questions such as: who contributes to the repositories and on what terms? Who uses the repositories? What do they contain and how fast are they growing, in terms of content and end use? What measures have repositories used to gain faculty and other researcher participation? How successful have these methods been? How has the repository been marketed and cataloged? What has been the financial impact? Data is broken out by size and type of institution for easier benchmarking.
