XI

With the tremendous recent growth of industrialism and the rapid multiplication of invention, the manifest need for making available the vast sum of gathered knowledge concerning the discoveries of modern science has evolved the great special libraries devoted to the varied subdivisions of the subject. Munificently endowed as many of them are, highly organized for ready access to material, administered to encourage use and to give expert aid as well, their great importance cannot be overestimated. What they accomplish is not wholly reducible to statistics, nor can their influence be readily traced, perhaps, to the great undertakings of today which overshadow the seven wonders of antiquity. But there can be no question that without the opportunities that here lie for study and research, and—no less important—without the skilled assistance freely rendered by librarian and bibliographer, special talent would often remain dormant and its possessor unsatisfied. Greater here would be the loss to society than to the individual.
