These publishers are trying out a new plan for marketing their group of adventure, detective and mystery stories. The enclosed circular gives the outline of the plan and a brief synopsis of the content of the fifteen titles. Galleys are not available on these books, so no appraisal can be made. The circulars are available in quantities of 50-200, and an elaborate advertising schedule is planned, which will cover the trade journals, the New York Times, Herald Tribune, Chicago Tribune, Chicago News, Boston Transcript, Philadelphia Inquirer, and Times Magazine. For larger distribution of promotion material, there is available a smaller circular for invoice mailings.
