HELDA ranks 54th on the international list of digital repositories

HELDA, the digital repository of the University of Helsinki, ranks 54th on the global list of publication archives.

Main reasons for the good placement on the list are visibility and high-quality contents. Visibility on this ranking list is determined simply by the quantity of links leading to HELDA.  As to contents, the most important factor is the number of scientific articles in the repository. The articles are counted with the help of Google Scholar –service.

HELDA is an open digital repository, maintained by the Helsinki University Library’s web-services. University members can save to the archive publications such as parts of research material and theses that are openly and publicly accessible. The object of HELDA is to enhance the visibility, use and impact of the university’s research publications.

The” Ranking Web of World repositories” is an initiative of the Cybermetrics Lab, a research group belonging to the Consejo Superior de Investigaciones Científicas (CSIC), the largest public research body in Spain.
