Stories for Young Hearts

«A learned college professor recently wrote me to ask: "For readers of what age are your books intended?" It puzzled me to answer that properly, until I had looked over some of the letters I have received. One says: "I'm a little boy 5 years old, and I just love your Oz stories. My sister, who is writing this for me, reads me the Oz books, but I wish I could read them myself." Another letter says: "I'm a great girl 13 years old, so you'll be surprised when I tell you I am not too old for the Oz stories." Here's another letter: "Since I was a young girl I've never missed getting a Baum book for Christmas. I'm married, now, but am as eager to get and read the Oz stories as ever." And still another writes: "My good wife and I, both more than 70 years of age, believe that we find more real enjoyment in your Oz books than in any other books we read." Considering these statements, I wrote the college professor that my books are intended for all those whose hearts are young no matter what their ages may be.»
