" HOW THE CONGRESSIONAL LIBRARY CARES FOR OLD NEWSPAPER FILES. In the Congressional Library at Washington, special efforts are made to preserve eighteenth century files. The volumes are sealed in dust proof cases. They are bound with buckram and finished with materials recommended by the best authorities.

Air that has been washed or screened to remove dust is forced through the stacks and then exhausted.
