Lane became the first biographer of Herbert Hoover, writing "The Making of Herbert Hoover" in 1920 in collaboration with Charles K. Field, editor of "Sunset" magazine. The book was published well before Hoover became president in 1929. A friend and defender of Hoover's for the remainder of her life, many of her personal papers would later be included in the Rose Wilder-Lane Collection at the Herbert Hoover Library in West Branch, Iowa. While Lane's papers contain little actual correspondence between them, the Hoover Post-Presidential Individual series contains a file of Rose's correspondence that spans from 1936–1963.
