so what exactly is the third databook? is it like a real book you can buy or like a site online?

All databooks and fanbooks are real books, published by Sueisha if I'm not mistaken. Omnibender - Talk - Contributions 04:15, August 10, 2010 (UTC)

is there some place where i can find translated versions of them.

Viz Media English Version Jan next year Edit

Viz Media is releasing this on 10th Jan 2012, if you've been waiting for an English databook. Check Amazon.—This unsigned comment was made by YaminoKami (talk • contribs) .
