The Horn Book Magazine, founded in Boston in 1924, is a bimonthly periodical about literature for children and young adults. The oldest of the magazines in the United States dedicated to reviewing children's literature, it began as a "suggestive purchase list" prepared by
Bertha Mahony Miller and
Elinor Whitney Field, proprietresses of the country's first bookstore for children, The Bookshop for Boys and Girls. Opened in 1916 in Boston as a project of the
Women's Educational and Industrial Union, the Bookshop closed in 1936, but
Horn Book continues in its mission to "blow the horn for fine books for boys and girls" as Mahony wrote in her first editorial.
