"This volume was developed in response to an urgent need for an instrument to authenticate unsigned texts of Poe that he could have inserted into the journals that he edited during his energetic editorial career: Southern Literary Messenger, Burton’s Gentleman’s Magazine, Graham’s Magazine, The Mirror, and the Broadway Journal. In addition it can and, I trust, will serve many other purposes for students of the words of Edgar Allan Poe: the analysis of his style and vocabulary, his characteristic and underlying concepts, his broad range of allusion, and his language transformations. There was an obvious need for such a key to the integrated body of his fiction, to accompany the 1941 Bradford Booth Claude Jones concordance to the very small corpus of his poetry."
