Adolescent resources on puberty are lacking in public libraries. Information is scattered, outdated, and non-inclusive of LBGTQ+ children and children of color. All adolescents need more relevant, accessible information on sexuality, reproduction, gender, and their changing bodies. This project assessed over 200 books and online resources for sexual and ethnic diversity. The Lake Oswego Public Library collection was improved with materials purchased, consolidated call numbers, annotated booklists, and a blog. A toolkit was created for use by other libraries. The library’s collection now reflects the experiences of its diverse patrons, with better access to resources for their safety and well-being.
