I am trying to find a particular Dragonlance book that I saw when I was a kid. I remember it being a large volume, possibly multiple books bound as one. I think that the cover had a white border.
In particular, I remember one section relating a visit to a city of gnomes. The book notes that in gnomish culture it is not considered impolite to interrupt someone when speaking because a gnome will prattle on forever if given the chance. I don't remember anything else.
