“The filming of books always causes a great demand for them. A call comes immediately after the advertisement appears in local newspapers and lasts months, and, in cases where pictures are extraordinarily good, years after the film has been shown. Before the exhibition of the pictures, ‘Peter Ibbetson’ stood on the shelf. Dumas was read by few, and interest in ‘The Four Horsemen of the Apocalypse’ lagged. Since the films have been shown here, these books are circulating constantly. “Not only do the films increase the demand for a particular book, but interest is aroused in the time and setting of the story. For instance, after ‘The Three Musketeers’ was shown, calls came for the life of Richelieu and the history of the reign of Charles First. Dumas is now in great demand. ‘Orphans of the Storm’ brought calls for the life of Danton and the history of the French Revolution. ‘Passion’ overwhelmed us with demands for the life of Dubarry and the life of Louis XIV.” _Walnut Hills Librarian, Cincinnati, Ohio._ “I can say, most emphatically, that the filming of literary classics does have a very noticeable effect upon the reading of the books filmed. The increase in the demand and use of these books is noticeable from the very moment they are announced. ‘Robin Hood’ is on here now, and long before it first appeared, every scrap of our information on Robin Hood was out in use. Recently this was true of ‘The Prisoner of Zenda,’ a subject which has been dead for quite some time in library circulation and all at once it was revived with a tremendous demand. Not long ago we had a sudden call from many parts of the city for material about ‘Fanchon the Cricket’ and later learned that the film had been running in an obscure community moving picture house.” _Charles E. Rusk, Librarian, Indianapolis, Ind._ “In some cases there is a demand for the books in foreign languages such as Italian and Hungarian, and the showing of ‘The Four Horsemen of the Apocalypse’ brought requests for the book in the original Spanish.” _Librarian of Public Library, Cleveland, Ohio._ “Very often not only the story filmed is called for, but others by the same author. In the case of ‘Monte Cristo,’ it has led to a great demand for all the works of Dumas. ‘A Connecticut Yankee in King Arthur’s Court’ has revived the interest in others of Mark Twain’s works.” _Report by a New England Librarian._
