Information literacy research is growing in importance but has been critiqued for remaining focused on practical topics of interest and attainment approaches to practice. Prior attempts to conceptualise information literacy have also often taken place without a comprehensive understanding of the ontological or epistemological foundations of theoretical work. The aim of this panel is to critically examine theory development and use within information literacy research through discussing the ways in which understandings of information literacy, including how it happens and how it shapes social life, are both enabled and constrained through critical, sociomaterial and discursive theoretical approaches. Providing a space to discuss and reflect on the impact of theory on information literacy scholarship, this panel creates a focal point for researchers, practitioners and students interested in the constructionand advancement of conceptually rich information literacy research and practice.
