摘要：This is a description of how the 70,000 volumes shelved in the old National Institutes of Health Library on the second floor of one building were moved into the fifth floor of a new building 300 yards away. By the use of book trucks, on which the books were placed in shelf order, and which were held together by giant rubber bands cut from automobile inner tubes, the need to pack books into heavy wooden crates was eliminated. The books were mass cleaned by blowing compressed air at 35 pounds pressure onto the book trucks at a speed of 300 volumes per minute. The total operation took seven 8-hour working daysof eleven workers, three of whom were-from the library staff, and the saving to the Institute from the bid of a commercial firm to do this work was $2759.
