Reflective dialogue asks us to pause before reacting, to ground ourselves in a sense of compassion for ourselves and others, and to use that grounding to open a space to listen and to speak with the goal of recognizing a shared humanity and appreciating difference. In four sections, Libraries Promoting Reflective Dialogue in a Time of Political Polarization explores the various ways in which librarians experience and respond to political polarization and its effects, both in our everyday work and in our professional communities.
