Five Dutch repositories in current Top One Hundred

The latest edition of the Ranking Web of World Repositories, provided by Cybermetrics Lab in Spain, includes five Dutch archives. The highest Dutch position is for the Igitur Archief in Utrecht on number fifteen, followed by the dissertation archive in Groningen on number nineteen.

At the top of the list is arXiv.org, a repository at Cornell University.  The Top Fifteen lists eight other repositories managed in the US, in addition to three French and two Swiss ones, and one at the United Nations.
The remaining three Dutch repositories in the Top One Hundred are at Leiden Universiteit (in 33rd position) and at the University of Twente: University of Twente is on 78 and EEMCS EPrints Service on 79. Links to all repositories are available on the web site of the Ranking Web of World Repositories.
This most recent edition is a Top 400 of repositories that meet certain requirements, such as having an autonomous domain name (that does not start with www), only concerning itself with scientific information, and archiving more than just a few journals. A repository’s position in the ranking is determined by its position in separate rankings for size, visibility on the web, the number of so-called rich files among which PDF and Excel files (the latter is new), and a score calculated with the aid of Google Scholar.
The web site of Cybermetrics Lab, which also publishes rankings of universities, hospitals, business schools and research centers, contains information regarding the methodology behind the Top 400.
