Becoming a more equitable librarian is an ongoing process. In the face of the last decade's events and increased public awareness of issues of diversity, equity, inclusion, and accessibility (DEIA), we in music libraries can do things to create the space in our teaching for optimal creativity and connection by and with our library users. Music Information Literacy: Inclusion and Advocacy imagines what it would be like to expand our inclusion structures so that we increasingly recognize and accommodate differences in our music libraries. The ways librarians teach and assist students must change to amplify the voices of those who have been traditionally marginalized and create effective and equitable libraries and classrooms. Doing so is a multi-part process, where critical information literacy overlaps with self-reflection as a librarian and a deep understanding that our students have identities and experiences that influence how they navigate their world. Many of our students have experienced trauma from the generational oppression of systemic racism, gender fluidity, invisible disabilities, discrimination, or poverty. Ongoing trauma triggers toxic stress that can rewire parts of the brain and impact one's ability to process information, formulate questions, and feel safe enough to be creative and in the zone of ideas. The chapters in the volume are authored by librarians who have actively been learning and self-reflecting on what is needed to invite users into their libraries and teaching spaces fully. The book is divided into Critical Theories, Concepts, & Reflections, Bringing Underrepresentation to the Forefront, and Supporting Activism. Each chapter includes case studies and discussion questions supporting ideas and concepts. A sample reading guide for each chapter is included as well.
