The Super Mario Bros. Encyclopedia was released in Japan in 2015 to celebrate the 30th anniversary of the franchise, but until now it has not been available outside of Nintendo's homeland.

According to a listing on Amaon UK, the encyclopedia will finally be translated and available to buy on June 15th 2017.  It is currently priced at £33.99.

The encyclopedia covers the mainline games from Super Mario Bros to Super Mario 3D World, featuring everything from characters to items and stages.  It is packed with concept art, interviews and developer notes.
