In order to conserve our time so that we may have leisure to give attention to individual children, we must arrange to have the mechanical part of the work as systematic as possible. Playground library work is a life of stress and strain. Everything comes in rushes. There is always a mad dash for the door as soon as the library is opened, for each child is sure that unless he is the first he will miss the good book that he is convinced is there. This rush of course makes it difficult to discharge the books, slip them, shelve them, and at the same time charge the ones the children have selected, to say nothing of helping the children in their choice. We have therefore found it best to collect the books beforehand, discharge them and distribute the cards among the children before opening the library doors. When the Newark system is used, however, and a child has drawn two books, this may result in considerable confusion, for the books may be separated and one may not be sure that both charges on the card should be cancelled. When our first playground library in Seattle opened, we used the Browne system of charging and this proved so satisfactory that we have continued to use it in the others. According to this method, each borrower receives two cards. When a book is borrowed, the book slip is drawn and put with one of the borrower's cards in a small envelope. It is readily seen how easy it is to avoid complications when the books are gathered before the opening of the library, for the slip of each one is with the borrower's card, and if the borrower returns no book, no card is given him. After the books are discharged and shelved and the cards distributed, the children are admitted. In this way much of the confusion incident to opening is eliminated and more time is secured to help the children make their choice. In order that the care of the books may not interfere with the children's play, we have devised a checking system by means of which the children may leave their books in charge of the librarian until they are ready to go home. This not only allows the children freedom in play but obviates the possibility of loss of books through their being left on benches and swings. The playground is a place of freedom and fun and good fellowship, and the library's rules should be made as inconspicuous as possible. The librarian should be not only willing, but anxious to enter into the life of the playground as far as her duties permit. One way in which she will be able to make herself popular not only with the children but with the instructors is by means of story telling. Joseph Lee says that story telling is the only passive occupation permissible on a playground and the librarian thus finds her work ready to her hand. She is able to advertise her books, make friends with the children is a most effective way, and at the same time relieve the playground instructor of a duty which is sometimes found irksome.
