During the Erasmus Staff Week, Liza Németh gained a comprehensive overview of the functioning of the libraries of the University of Liège, including the organizational structure, collection management and heritage protection tasks. The program's highlights included the application of artificial intelligence in libraries, Open Science practices, and the support of the Diamond Open Access model through the BeDiamond initiative. The visit offered valuable professional experiences and inspiring good practices that can be directly used in everyday work and professional development.
