I wish there would be an English translation of the guidebook, but I doubt it. So far none of the five(I think?) Steins;Gate guidebooks (EDIT: Oh yeah, there're also the anime guidebook and movie info book... so that'd be 7 if you want to count those.) have been translated and published for the English market as far as I know.

However, I've been/am using four of them while working on this wiki, so some of their information is available through here, but not all (yet) and some pages on this wiki need a major overhaul to get them up to date with all of the new information available since the articles/comments were written quite awhile ago.
