You betcha. The trick to searching for recipes books in our db is they're "Knowledge" (I gotta look into that one of these days). Try this
advanced search. I think we have
most of the tinker books. Clicking on any book will show you where it dropped (or was bought) if we know.
Edit: I do know that your next stop for tinker books is Steamfont :)
