Watchdogs of Democracy?: The waning Washington press corps and how it failed the public by Helen Thomas is the book to read! I have just finished reading the book and if anyone is interested in journalism, I would recommend this book. To me it was like getting a history lesson about journalism and it gave me some insight on what reporters do. In the book she wrote "Without an informed people there can be no democracy" Yea, that is such a profound statement!
Helen Thomas has been a journalist for over sixty years and has been a member of the White House press corp since the Kennedy years. If you can't buy the book right now, go to your local library and ask them to order it.
