Doubleday's first printing was 218,000; the count now is just over 1.5 million after 23 trips to press. The Pocket Books mass market edition of an earlier Brown title, Angels and Demons, which introduced Robert Langdon, who returns in The Da Vinci Code, marks 17 weeks on the PW charts and has 725,000 copies in print; the hardcover Atria edition is up to 50,000 copies in print. Atria will reissue another Brown title, Deception Point, in September, with a 30,000-copy printing.
