Public library provides recreation. It preserves the literary remains of humanity for posterity, as a vehicle of culture and as source material for antiquarian research. It works for continued social wellbeing, as the agency in charge of all socialized recorded thought. Public library discharges educational, informational, political, economic, industrial, cultural, and antiquarian functions. Thus, the true function of the library is to permit and encourage men to grow up and achieve maturity in an atmosphere of freedom that they may feel that life has something to give them and them something to give it. A world well provided with free libraries would be a world of happy, sensible, peaceful, constructive men, and also a world of immense variety, excitement, and adventure. A public library provides an opportunity for reading books which foster a full and good life. It enables a person to utilize his innate abilities for the benefit of the society. To sum up, it acts as a living force for education, culture, and information as an essential agent for the fostering of peace and understanding between people and nations.
