Notes: DSA YEarbook is a short section at the back of all books in the series published 2003 or later. (I can only confirm that it is in books 1-11 published in the US, however it seems likely that they continued the practice.) It consists of new illustrations by Mr. Basso, and short biographical sketches of some of the main characters of the books. It is exactly the same in books 1-11. Not sure if it changes after this.
