This article explores the work of tool lending libraries from the perspective of staff and decision makers. It addresses what role serving community members with tools plays, and what this in turn means for the professional role of library work. The study builds on semi-structured interviews with tool lending specialists and managers from three US municipalities. Participants are found to perceive their library and their work as something of practical, local and immediate relevance. Compared to traditional library work, participants perceive their setting to require patrons and staff to be more directly and actively social. Several participants stress the importance of staff being experienced tool users themselves, leading the article to conclude with a discussion on reference competence.
