Open-access repositories worldwide, 2005–2012: Past growth, current characteristics, and future possibilities

A new article on OpenDOAR has recently been published:

Open-access repositories worldwide, 2005–2012: Past growth, current characteristics, and future possibilities, S Pinfield, J Salter, P Bath, B Hubbard, P Millington, JHS Anders & A Hussain, Journal of the American Society for Information Science and Technology, Early View 28 APR 2014

Also available open access as the accepted version here:

“This paper reviews the worldwide growth of open-access (OA) repositories, December 2005 to December 2012, using data collected by the OpenDOAR project. It shows that initial repository development was focused on North America, Western Europe and Australasia, particularly the USA, UK, Germany and Australia. Soon after, Japan increased its repository numbers. Since 2010, other geographical areas and countries have seen repository growth, including East Asia (especially Taiwan), South America (especially Brazil) and Eastern Europe (especially Poland). During the whole period, countries such as France, Italy and Spain have maintained steady growth, whereas countries such as China and Russia have experienced relatively low levels of growth. Globally, repositories are predominantly institutional, multidisciplinary and English-language-based. They typically use open-source OAI-compliant repository software but remain immature in terms of explicit licensing arrangements. Whilst the size of repositories is difficult to assess accurately, the available data indicate that a small number of large repositories and a large number of small repositories make up the repository landscape. These trends and characteristics are analyzed using Innovation Diffusion Theory (IDT) building on previous studies. IDT is shown to provide a useful explanatory framework for understanding repository adoption at various levels: global, national, organizational and individual. Major factors affecting both the initial development of repositories and their take up by users are identified, including IT infrastructure, language, cultural factors, policy initiatives, awareness-raising activity and usage mandates. It is argued that mandates in particular are likely to play a crucial role in determining future repository development.”

Merry Christmas and a Happy New Year

It is that time of year again, when we all aim to take a well-earned day or two off work. As a result, SHERPA Services (RoMEO, JULIET, FACT and OpenDOAR) will be on reduced staffing from the 13th December 2013 until the 6th January 2014. All enquiries will be answered in due course.

In additional news, due to scheduled maintenance, there may be some disruption to SHERPA Services (RoMEO, JULIET, FACT and OpenDOAR) on the evening of Tuesday 17th December 2013. We apologise for any inconvenience that this causes.

We wish you all a Merry Christmas and Happy New Year.

The Fate of Suggested OpenDOAR Additions

We have recently updated the chart showing the growth and fate of OpenDOAR suggestions over time:

Suggestion Outcomes by Year for OpenDOAR

Suggestion Outcomes by Year for OpenDOAR

The overall annual number of suggestions has grown steadily, but the rejection rate has remained steady at about 22% of suggestions. There was a significant problem with spam during OpenDOAR’s first two years. We added spam blocking functions to the Suggestions form in 2007, which significantly reduced the amount of spam received, and which seems to be staying at a reassuringly low level.

See for the chart full size and for further information on the various reasons for rejection.
