The mystery is solved! E.B. stands for Elywn Brooks. As an elementary school teacher, I found the information in this book useful. Beyond the basic information about his life, the book chronicles his journey as a writer, beginning at a very early age. The chapters devoted to Charlotte's Web, Stuart Little, and The Trumpet of the Swan give interesting facts about the writing of these books. There are even pictures of his original manuscript for Charlotte's Web, showing his revision marks. I am going to use these particular chapters to help with writing mini-lessons about pre-writing and revision.
