Created by the Stratemeyer Syndicate, the Blythe Girls series was published by Grosset and Dunlap from 1925 through 1932. Whitman later reprinted volumes 1 through 4.
Illustrator for the G&D books was Thelma Gooch.
Elizabeth M. Duffield Ward wrote the series under the popular Stratemeyer Syndicate house name of Laura Lee Hope. Ward also wrote volumes 7 through 23 of the Outdoor Girls series.
This series followed a pattern: first, a title about all three girls, followed by books centering on Margy, Rose and Helen, in that order, the cycle then repeated.
"These stories relate the experiences of the three Blythe girls who were left alone to make their way in the big city of New York. Every young girl with want to know how they succeeded." - G&D advertisment.
