should be made for interchanging, and all necessary facilities provided for enabling intelligent young people under the limit to procure suitable more advanced books if desired, and also for allowing adults to revive their youth by allowing them access to the works of Ballantyne, Henty and other authors. =351.= As regards age limits in reference libraries and reading rooms, there is more to be said for keeping them high than in the case of lending libraries, especially when there are separate children’s rooms. But, generally speaking, there is no strong reason for excluding well-conducted boys or girls from a popular reading room, whatever their ages may be, provided they do not come during school hours, or do not otherwise make the library a place in which to hide from some duty. In some libraries, with age limits of twelve, fourteen or over, it is the practice to turn away younger children from news and reading rooms in cases where they are accompanied by their parents or elders. This is an abuse of a rule which was only intended to protect readers from the noisy incursions of irresponsible youngsters, who are wont to stray into public places out of sheer devilment, or accident, or excess of curiosity. To apply this rule to children in arms, or youngsters accompanied by and in charge of their elders, is simply officialism calculated to injure the popularity and prestige of municipal libraries. The age limit for a reference library designed for students, with open access to the shelves, should be fixed at fourteen or sixteen, with discretionary power to the librarian to grant permits to any studious youngster under that age. Where access to public reading rooms and juvenile departments is easy, there seems no good reason for throwing open the reference library to all and sundry, unless under the safeguards suggested.
