Children's books published between 1910 and 1960 reflect a changing world and new attitudes toward children. In 1910, although some of the moral tales of the earlier Puritan era survived, the didactic period in children's books was nearly over. From 1910 to 1925, a transitional period, writers began to look toward the children's own world. Then, "the golden age of children's books," 1925-1940, saw an influx of foreign authors, the flowering of the American picture book, and the appearance of stories about real boys and girls. Because of the war, children's books between 1940 and 1950 attempted to maintain old values and establish new ones. Finally, complex trends between 1950 and 1960 involved the appearance of paperbacks for children and books of information written for various reading levels. (Lists of children's books, a bibliography of information about children's books, and a directory of publishing companies are given in this book.) (JS)
