Abstract
Purpose
The overarching aim of this article is to consider to what extent the perceptions of librarians in Denmark, Germany, Hungary, Iceland, Norway, Poland and Sweden reflect a unified view of their professional role and the role of their institutions in supporting the formation of the public sphere and to what extent the variations reflect national contexts.

Design/methodology/approach
The multi-country comparison is based on online questionnaires. The central research questions are how do librarians legitimize the use of public resources to uphold a public library service? How do librarians perceive the role of public libraries as public spaces? How do librarians perceive their professional role and the competencies needed for it? Consideration is given to how the digital and social turns are reflected in the responses.

Findings
The results show evidence of a unified professional culture with clear influences from national contexts. A key finding is that librarians see giving access as central for both legitimizing library services and for the library's role as a public sphere institution. Strong support is shown for the social turn in supporting the formation of the public sphere while the digital turn appears to be a future challenge; one of seemingly increased importance due to the pandemic.

Research limitations/implications
This study shows that libraries across the seven countries have expanded beyond simply providing public access to their book-based collections and now serve as social, learning and creative spaces: both in the physical library and digitally. Qualitative research is needed concerning librarians' notions of public libraries and librarianship, which will provide a more in-depth understanding of the changing professional responsibilities and how public libraries recruit the associated competencies.

Originality/value
The article provides a much needed insight into how librarians perceive the role of public libraries in supporting the formation of the public sphere and democratic processes, as well as their own role.
