Swapping Books-Scene here yesterday, as the Merchant Marine Library Association and the Russian War Relief exchanged books, to the advantage of all concerned. The Russian group acquired English classics for the looted library shelves of Russia, in exchange for popular fiction to lighten the hours of American merchant seamen. The "traders," left to right-Miss Charlotte Kaizer, Mrs. Tamara McIntyre, Brooks Jenkins, librarian of the association, and Prof. Theodore Spencer, chairman of the "Books for Russia" campaign
