This project addresses the scarcity of resources in trauma-informed librarianship (TIL) by drawing on literature in trauma-informed care and pedagogy to create a book structured to equip librarians with foundational knowledge and practical implementation strategies. Divided into two sections, the book begins with the fundamentals of trauma- informed practices, then moves to TIL. Introducing six principles of TIL, each chapter offers theory and practical insights. By fostering understanding and offering actionable guidance, this project seeks to revolutionize library services, ensuring they are equitable and accessible for all, acknowledging the impact of trauma on individuals' engagement with information and community resources.
