The institutional repositories contributes to the promotion of the results of scientific research, increasing the prestige of the educational institution in a national and international aspect, and provides access to published scientific production. At the same time, the development process of the repository in terms of technology and content requires librarians to have specific professional skills for archiving and indexing the received documents. In accordance with the Code of Ethics, the librarian implements and ensures compliance with the principle of continuous professional development, participating in training and improvement programs, professional meetings, scientific and cultural activities organized by libraries or other institutions. At the same time, the librarian’s professional deontology presupposes librarians’ self-training and their responsibility for their own training. The success of the university library activity oriented towards the needs of the users involves two conditions: access to quality information services and products, on the one hand, and well-trained and highly qualified librarians, who deepen and constantly update their specialized knowledge and skills, necessary for the exercise the functional attributions it has, on the other hand.
