What does "colophon" mean?

Colophon: An inscription, monogram, or cipher, containing the place and date of publication, printer's name, etc., formerly placed on the last page of a book. The colophon, or final description, fell into disuse, and . . . the title page had become the principal direct means of identifying the book. De Morgan. The book was uninjured from title page to colophon. Sir W. Scott.
