Colophon
A colophon is a short note, usually on the last page, recording how the book was made — the typeface used, sometimes the paper, press or designer. It is optional and quietly signals craft.
Historically the colophon carried the printer's imprint at the end of the book, before title pages became standard. Modern trade publishers keep it as a note on the type: a sentence or two naming the face, its designer and its date. For a self-published book it is a cheap piece of polish — three lines that tell a reader the interior was chosen rather than defaulted — but it is a claim, so only write it if the face named is the one actually used.
