idea for further reading i am proposing the addition of a further reading section to this article i have recently come across a book that i think would add more depth and breadth to the topic it is titled the discovery of the bismarck by robert d ballard who is an authoritative figure on the subject of the german battleship bismark since he was part of the crew that rediscovered the sunken wreck in and has already written another book already referenced in this article the book contains an in depth history of the ship bismarck from different historical perspectives from all the ships involved in it's sinking as well as documentation on the methodology and events of the ship that discovered the wreck
