Science as we know it today would be simply impossible without a multitude of critical services that enable scientists to connect and to collaborate, to share and to disseminate knowledge.

Who should build it and make it available? Who may use it and who may not? Our next dossier will deal with the topic of research infrastructure. Join us on the search for answers in the upcoming weeks!
