Primary Research Group has published The Survey of Institutional Digital
Repositories, 2011 Edition, ISBN 157440-161-0.
The 225-page report looks closely at how 60+ academic and special libraries and other select institutions in the United States, the UK, continental Europe, Canada, China, India, Australia and other countries or regions are funding, managing, cataloging, marketing and developing their institutional digital repositories.
The report provides detailed data on budget and spending, sources of revenue and support, man hours deployed, range of materials maintained, number and source of visitors and downloads, and other key facts about institutional digital repositories.
The report also looks closely at the degree of faculty cooperation, methods of procuring and measuring this cooperation, plans to develop repositories as publishers in their own right, impact on the online presence of the college and on citation rates in journals, among other issues. Data is broken out by size, geographic region, Carnegie class, years in operation and type of library or other institution (such as scientific institutes).
Just a few of the study’s many findings are that:
• The repositories in the sample received a mean number of 375,919 unique
visitors in the past year with a median of 33,210.
• 52.4% of the survey participants housed books written by faculty or
staff in their digital repositories. This was most common in Europe (nearly
77%) and least common in the developing world (12.5%).
• Nearly 58% archived digital images, a practice most common in the USA,
especially among research universities.
• For the sample as a whole, 4.45% of repository downloads come from
• Close to 33% of the survey takers have an interface that allows authors
and other some other contributors to track their downloads.
• A mean of 32.3% of visitors to the repositories are from the
repository’s own institution; the median figure was 12.75%.
• 39% of survey participants had a brochure for their digital repository;
half of all European repositories had a brochure.
• 15.79% of repositories have an E-publishing program through which they
publish monographs or books in either a print or digital format that might not have been initially published elsewhere.
