Swedish National Data Service (SND) is a research data infrastructure that supports accessibility, preservation, and reuse of research data. The SND Search function makes it easy to find, use, and cite research data from a variety of scientific disciplines. SND is present throughout the Swedish research ecology, through an extensive network across closer to 40 higher education institutions and other research organisations. Together, SND and this network form a distributed system of certified research data repositories with the SND main office as a central node. The certification means that SND ensures that research data are managed, stored, and made accessible in a secure and sustainable manner, today and for the future. SND collaborates with various international stakeholders in order to advance global access to research data.
