What is a description of the typeface used in a printed book called?

The term used to describe the typeface in a printed book is known as a colophon. A colophon typically appears at the end of a book and includes information about the book's production, such as the typeface used, the paper specifications, and the printing process. This information offers insights into the design and aesthetic choices made during the production of the book, helping readers and bibliophiles appreciate the craftsmanship involved in its creation.

Other terms, such as index, foreword, and appendix, refer to different components of a book. An index is a list of names, topics, or keywords along with page numbers that helps readers locate information within the text. A foreword is a preface or introductory section that is usually written by someone other than the author, providing context or insights about the book. An appendix includes supplementary material or additional information relevant to the main text, often found at the end of the book. Each of these terms serves distinct purposes in a book, highlighting why the colophon is the correct choice for describing the typeface used in the printed work.
