Children's Book Week is an annual celebration dedicated to promoting reading and literacy among children. It typically takes place in May and encourages families, schools, and libraries to engage in activities that highlight the importance of children's literature. The event features various programs, including author visits, book fairs, and reading challenges. Established in 1919, Children's Book Week is the longest-running national literacy initiative in the United States. It is organized by the Children's Book Council, which collaborates with schools and libraries to inspire a love of reading. Each year, a theme is chosen to guide the celebrations and activities.
