Almost Weeded a Very Precious Book

My family can tell you that I am not a saver. I discard things that are no longer needed. As I was weeding the AOSR Library there the book, The Story of My Life, by Helen Keller. There were two copies. One was old and the other was new. So I decided to discard the old copy. I didn't check the title page but thankfully a teacher found the book in my discard pile and told me this was a precious book. It has been signed by Helen Keller when she visited the school in 1947. The book is now in a safe place. - Nancy
