In connection with the above review of the life of Cyrus Hall McCormick it is appropriate to say something about the McCormick Historical Association. This organization has purposes which relate closely to the objects of the Business Historical Society, and the materials which it has gathered together constitute an important source of business history which should be known to all students of the subject. The McCormick Historical Association has been building up an intensive collection of printed manuscript and museum materials at the McCormick Library, 679 Rush Street, Chicago. The items relate to a rather wide range of topics but they center in the activities and interests of Cyrus Hall McCormick and the McCormick family.
