A study undertaken by AASL’s Community of Scholars provides an aggregation and systematic review of research related to school librarian practice published in 2019.The AASL Strategic Plan (2019) also included five core values: learning; innovation; equity, diversity, and inclusion; intellectual freedom; and collaboration. The researchers found the “core values to be tightly intertwined in the research. Learning outcomes were a focus in nearly 50% of the studies, but learning was a component of much of the remaining research in innovation and collaboration.”
