On 27 October 2022, the community of librarians participated in a training session on citizen science and the role of librarians in this field at the KTU campus library. Aistė Pranckutė, the LibOCS project specialist, introduced the concept and the basic definitions in citizen science and presented the global and Lithuanian citizen science projects. The international ERASMUS+ partnership project LibOCS, in which KTU is participating as one of the partners, was also presented, as well as its goals, initial results, and planned activities. One of the activities is the development of training material for librarians. The project specialist expressed her hope that citizen science and the opportunities to participate in its activities would interest colleagues and encourage them to participate in further activities organized by the project.
