The official historian of the U.S.O. records that organization in somewhat the way that George Korson in At His Side chronicled the activities of the Red Cross, through the media of the workers, through letters, club reports, dialogue, incident and illustration. Excusably sentimental at times, excusably enthusiastic, here is the U.S.O. as it provided coffee and doughnuts, cold milk and warm shoulders for service men in all parts of the world. Here is how the U.S.O. functioned at birthdays and weddings; in layovers overseas; in clubs. Here are the camp shows and entertainments they provided; the mobile units; the Victory books; the letters written to families at home; and on occasion, the intrusion and interference to good ends. Here are all the ways they operated to make wartime living more livable. U.S.O. participators will be the primary market for this, which makes the book seem timed too late.
