The Super Mario Bros. Encyclopedia was released in Japan back in 2015, but was never announced for release in any other regions. However, it looks like Nintendo is working with publishers outside of Japan to push the book out overseas.

To anyone unfamiliar with the Super Mario Bros. Encyclopedia, the book is a 256-page book with art and information for 17 different games in the series.

Amazon UK, Amazon Germany and Amazon France all have the encyclopedia up for pre-order, while Amazon US and Amazon Canada simply have the book listed and not available for pre-order.

Every listing points to a June 15th release.
