A new toolkit by the Association for Library Service to Children’s Library Service to Underserved Children and their Caregivers committee offers resources for working with the 44 million people in the United States who were born in another country. The toolkit includes information on programs and services; communications and marketing; library collections; stakeholders and partnerships; and equipping staff. Additional sections, available later this year, will discuss recommended read-alouds and provide examples of programming and outreach. The toolkit is part of the committee’s larger series of toolkits providing resources for working with traditionally marginalized populations.
