Between 2015 and 2017, the presenters have interviewed more than 75 library directors and leaders, library assessment practitioners, and academic experts on four continents about library assessment and its current state in their institutions. The results reveal a varied landscape, with libraries in widely varying stages of assessment performance and readiness. This paper will draw a picture of the current landscape of library assessment based on the data gathered in these interviews. The authors will focus specifically on the continuum between micro and strategic assessment and share the lessons learned from diverse institutions and geographies about how to build a culture of assessment.
