A man browses the racks of circulating paperback books located in the first floor lobby of Central Library, near the Popular Library. Twice a year library staff selected and purchased 10-100 copies of popular titles that had become available in paperback. Those paperbacks weren't fully cataloged however a simple author/title record was created for circulation purposes. Transcribed from back of photo: 'Empty shelves testify to the use made of the paper-back collection'.
