Feminism is important in public libraries and teen spaces because it ensures that we think critically about the services we offer our patrons. Because a feminist analysis recognises vast systems of oppressions, not just those centred around binary gender roles, feminism offers a powerful framework for ensuring that libraries are safe, inclusive spaces that facilitate learning, information sharing, and discussions, including on tough topics. This issue of the YA Hotline offers an introduction to intersectional feminist values as they apply to teen services, teen programming, and YA literature.
