What in the world is a MOOK?

Epson R-D1 World, originally uploaded by benny ng.

I think this word only exist in Japan. It's a cross between Magazine and bOOK.

Similarly, the content is much more substantial than a magazine, but less 'heavy' compared to a full fledge reference book. And of course, like magazines, it's plastered with loads of pictures. In Japan, you can find MOOKs for just about anything. Watches, Luxury Brands, Cars, and of course cameras!

I think this must be the only publication on Epson R-D1.

Cheers,
