Nancy Drew Mystery Stories was a series of books attributed to Carolyn Keene. Of the 56 titles published between 1930 and 1979, the initial 34 were revised (many of them extensively) between 1959 and 1977; these revised 34 titles and the remaining 22 titles published between 1959 and 1979 are now considered the canon of Nancy Drew. These books were published as unjacketed hardcovers by Grosset and Dunlap. This series was followed by a second series of titles published by Simon & Schuster between 1979 and 2003; the first eight of these titles were reissued by Grosset and Dunlap in 2005.
