The wiki should probably have pages for the official guide books, just like it does for graphic novels, activity books, etc.

I can provide ISBNs, publisher, page count etc. for the ones I own.

The Sonic Retro wiki has a bunch, but they're missing a few as well: http://info.sonicretro.org/Category:Strategy_guides
