The Kingdom the the Dwarfs was a book printed at about this time, aimed at Lord of the Rings aficionados. Here it appears in the advertising section – books that the readers might like.

I used to have a copy of this book at one point and remember thinking that it read like an advertisement for a much longer, more comprehensive work.
