One of my favorite parts of making limited edition books is creating the colophon. Often prefaced with "A note on the type", the colophon page sometimes describes the history of the typeface featured, and I've seen a few that even explain a little bit about why the editors or author chose that particular font.
Survey your shelves for books published by Knopf, and take a look at their colophons. This publishing house apparently takes great pleasure in these little details.
An often overlooked gem in print: the colophon!
