The document discusses creating a community vision for STEM programming at public libraries in the 21st century. It emphasizes that libraries should first discuss goals, challenges, and priorities with their staff to define a core mission. Libraries should then assess the needs of their community through outreach to determine what types of STEM programming - for children, adults, or both - would have the most impact. The document stresses that while most librarians are not scientists, libraries can partner with experts and inspire patrons of all ages through literature to introduce them to STEM in new and engaging ways.
