Our library is primarily a deposit branch of the Chicago public library. We have about 1600 books on deposit, which give us a circulation of about 4000 a month. In addition to that, our daily express service gives us the resources of the main library stock, and makes it possible to send individual cards with specific requests through the station department. This is a great help in making out lists on special topics, as 25 or 30 books on a subject may be listed and drawn one after the other without further reference. Our circulation for these books runs from between 75 to 100 a day. In addition to our public library books, we have about a thousand of our own. About 75 per cent. of this collection is light fiction and juvenile books; that is, stories for both boys and girls of the intermediate age. Books of this character are, of course, in the greatest demand, and it is for the right kind of this material that we are constantly searching. This supplementary collection of our own does not in any way detract from our public library books, but rather serves as added bait and leads to the better books of the public library, upon whose resources we depend for our existence. We subscribe for about 40 monthly and weekly periodicals, both technical and popular. In addition to these, we have several shelves of miscellaneous magazines, composed of month-old copies sent out from the main library, as well as our own old copies, and donations from the employees. All of these magazines we circulate. In fact, we are in no sense a reading room, as the very nature of a busy 8-hour day and 45-minute lunch period will prove. Our charging tray and a few pieces of furniture are the only things we refuse to let go to the homes or departments. In taking charge of the library last fall, I realized that there were two distinct phases of the work: the commercial or economic, and the social--the first to be established, the second to be developed--both sides equally interesting and offering equal possibilities. The commercial value must be established not only by becoming familiar with the policy of the house, but by co-operating with the heads of departments and making the library felt as a live agent throughout the house.
