It looks like Bing hopes to gain a foothold in the interactive campaign space with the launch of a complex international, interactive marketing campaign for Jay-Z’s new book, Decoded.

Jay-Z is hiding 300 pages of his new book around the world…fans get to find them. Jay-Z fans will be able to access pages from the his upcoming book — Decoded, an exploration of his life and lyrics — until November 16th, 2010.

Here’s how it works: Pages from the book will be physically placed around the world with a majority in the New York area, in locations related to specific content featured on Bing — specifically Bing Maps and Bing Entertainment. Five to 10 new pages from the book will be revealed each day; fans can find them in person or online.

Once players locate a page, they will get credit for it online. If they find it in a physical location, they will be able to text a unique game code from the page. Players will be entered into drawings to win a signed copy of the page they’ve located. And everyone who locates a page will be entered into a contest for the grand prize — two tickets to see Jay-Z and Coldplay in concert at Las Vegas on New Year’s Eve.
