Work with children is so large in its scope and so rich in its possibilities that we shall only consider work in the library proper, passing over home visiting, school visiting and cooperation with social settlements and like institutions, all of which, however, are of the greatest importance to the work as a whole. Work with children may be grouped under three heads-- that with girls, that with boys and that with little children. While in each group the work differs in nearly every point, one point they have in common--the choosing of fiction according to the individual child, boy or girl; the choosing of classed books for the book itself. In giving fiction, the child must be known as well as the book, his character and needs, for it is on the character that fiction has most influence. In classed books, on the other hand, the book is the thing to know, for if a child wants to know something about electricity or carpentry, he is not being influenced so much in character as in education. If the book is not as good as some other, it will not injure him especially as to morals and character, but of course he should have the very best you can give him that he can mentally understand. Girls almost always become interested in books through the personality of the children's worker. While it is very desirable to use this regard as a means of influencing their reading, care must be taken to guard against a merely sentimental attitude on the part of the girls toward the worker. As a rule, girls want stories about people, other girls, school stories and so forth, and will take a book that you say is a good one without looking into it. If she likes it she will come to you to select another, and in this way you can lead her from pure fiction to historical fiction and biography and so on up to good literature, all through, at the first, knowing a book that would please and attract her. This is done, in great measure, through the girl's liking for the worker and also through her interest in people rather than things. Boys, on the other hand, are not so much interested in people as in things, and when they ask for a book it is usually on some specific subject--electricity, carpentry, how to raise pigeons, how to take care of dogs. When the book is given them they usually examine it pretty thoroughly to see whether or not it is what they want or can use. To know what book will give the boy what he wants to know and in the most interesting way is to gain that boy's confidence. To sum up: Boys like you through the books you give them, while girls learn to like good books through their liking for you. The result is the same in either case--the personal influence of the worker with the children.
