What is one of the characteristics of a book that indicates it has an author?

A title page is a characteristic of a book that distinctly indicates it has an author because it typically includes the name of the author along with the title of the book and sometimes the publisher’s information. This page serves as a formal introduction to the book and establishes the authorship, which is crucial in identifying who created the content. While elements like a table of contents, illustrations, and binding contribute to the overall structure and presentation of the book, they do not serve as direct indicators of authorship. A table of contents organizes the content within the book, illustrations enhance the visual experience, and binding refers to the physical assembly of the book itself, but none of these elements specifically attribute the work to an author.
