Over the course of World War II, the Dutch Navy lost seven submarines – six of which disappeared in unknown locations. Since then, five have been recovered, and the search for the final submarine, designated O13, is the subject of a documentary by filmmaker Wilco Pleging.

To accompany the documentary, a book has been published containing stories, documents, drawings, photographs and more. But this book, O13: Still On Patrol, is unlike any other. The pages have been made interactive with the Layar Creator and the publisher plans to regularly update the content with new information.

Right now, book readers can scan the book with Layar for access to copies of the original construction plans of the O13, new photos from the search for the ship and more. Each week for the next few months, readers can enjoy more new extra digital content by scanning pages with the Layar App.

It’s not the first time we’ve seen publishers enhancing books with Layar, but the regular updates are unique in this case. This is a great way to bring more interactivity to books. By being promised more content each week, readers will be eager to pick up the book again and again.
