To help school librarians develop learners' abilities to contribute to teams that can capitalize on a diversity of thinking and perspective, AASL tasked a 2024 ALA Emerging Leaders team with creating a guide for school librarians based on the Collaborate Shared Foundation in the "National School Library Standards." Working effectively in teams means being able to listen to, learn from, and share with others. This collection of activities and web resources, pushes school librarians, educators, and learners to build collaborative capacity in themselves and their learning communities. Successful collaboration requires empathy and welcoming diverse perspectives. By inviting and fostering collaboration, school librarians embody the message that everybody is welcome in the school library. "Developing Creative Collaborators, Flexible Partners, and Resilient Citizens" is loaded with ideas for cultivating collaborative learners and communities.
