The first four titles were published in 1930 and were an immediate success. Exact sales figures are not available for the years prior to 1979, but an indication of the books' popularity can be seen in a letter that Laura Harris, a Grosset and Dunlap editor, wrote to the Syndicate in 1931: "Can you let us have the manuscript as soon as possible, and no later than July 10? There will only be three or four titles brought out then and the Nancy Drew is one of the most important." The 6,000 copies that Macy's ordered for the 1933 Christmas season sold out within days. In 1934 "Fortune" magazine featured the Syndicate in a cover story and singled Nancy Drew out for particular attention: "Nancy is the greatest phenomenon among all the fifty-centers. She is a best seller. How she crashed a Valhalla that had been rigidly restricted to the male of her species is a mystery even to her publishers."
