This thesis examines the impact of the project Boken kommer 2.0 on librarians’ professional practice within the public library system in Gothenburg, Sweden. In addition to the project's specific influence, the study explores broader organizational changes related to centralization and efficiency measures. Employing a qualitative case study methodology, interviews were conducted with four librarians possessing direct experience of Boken kommer. Several findings emerged from the study. One finding suggests that the professional role of some librarians is expanding, leading to a potential blurring of role boundaries and a less clearly defined professional status. Changes within the organization have enabled several librarians to engage in new additional duties. Competencies linked to the former work practice with Boken kommer appear to be redistributed, rather than being lost. Another finding suggests that librarians may experience a general reduction in competence due to centralization and efficiency measures. Despite these developments, librarians demonstrate a high degree of adaptability and changes are generally met without resistance. This study contributes to the understanding of how structural transformations within public libraries influence professional roles and practices, highlighting the evolving nature of librarianship in response to institutional change. The study confirmes the ongoing discussion about librarians often vague job desciption and indicates a constant professional fluidity, wich may lead to continued difficulties in stablishing librariansship as a recognized profession.
