Every year the Library of the University of Latvia hosts guests from ERASMUS+ mobility programmes. This year, in May and June 2024, guests were welcomed on several occasions, from different countries: Sweden, Romania, Germany. Guests were given demonstrations of the work processes in the library and briefed about collaboration in an academic environment. During the visit, the library also presented its services and development plans in the context of open science, including LibOCS. The guests were very interested in the idea and results of the LibOCS project.
