How can the principles of Open Science be implemented in European research libraries to enable world-class research? A LIBER working group has addressed this question and developed appropriate training methods and practices. Cécile Swiatek was one of the persons who led the working group and presents the results in an interview. She also tells us why libraries are perfectly suited to play a key role in the change towards an open culture and why it is so important to build networks and share knowledge in this process.
