This book serves as a readers' advisory and collection development resource for youth services and school librarians seeking to bring STEM-related titles into their collections and introduce teachers and young readers to them. This book not only guides readers to hundreds of the best STEM-related titles-fiction and non-fiction printed materials as well as apps, DVDs, websites, and games-it also includes related activities or programming ideas to help promote the use of the collection to patrons or students in story time, afterschool programs, or passive library programs.
