The printing press puts into the hands of parents a means of good, which they may use to the greatest advantage in the culture of their home-life, and in the shaping of the lives of their household. But they must keep a most diligent watch over the pages which they introduce. They should know the character of every book and magazine which comes within their doors, and should resolutely exclude everything which would defile. Then, while they exclude everything whose influence would be for evil, if they are wise they will bring into their home as much as possible of pure, elevating, and refining literature. Every beautiful thought which enters a child's mind, adds to the strength and loveliness of the character in after days. The educating influence of the best books and magazines is incalculable, and no parent can afford to lose it in the training of his family.
(J. R. Miller, "Home-making" 1882)
