This interpretive focused-ethnographic study was conducted to illuminate and gain deeper understanding on managers’ everyday cooperative work practices using artefacts. In the dissertation, artefacts refer to digital technologies and information. The doctoral research specifically examines how artefacts in the workplace of an academic library are used in academic library managers’ everyday cooperative work practices; and provide suggestions of how artefacts can be used to better fit those practices. The empirical data was collected through participant observations, face-to-face interviews and documents from two technologically advanced academic libraries, one in Sweden and another one in Australia. The study uses soft systems thinking theory and concepts from computer-supported cooperative work (CSCW) such as awareness, articulation and appropriation to analyze and discuss how cooperative work is conducted in the everyday work practices of academic library managers with the use of artefacts. Thus, this research contributes insights from the field of computer-supported cooperative work to the information systems and library domain by considering social aspects of cooperative everyday work practices.
