Book

The Book schema type describes a published book — whether print, ebook, or audiobook. It powers Google's book knowledge panel, links readers to retailers, and helps libraries and search assistants disambiguate titles by ISBN and format.

About Book

Use Book markup on dedicated title pages on a publisher, author, or review site. The isbn field is the canonical identifier search engines and AI assistants use to merge data from multiple sources, so always include it when known. Pair Book with an AggregateRating block on review pages, and link the author via the Person type so your knowledge graph stays connected.

`name`	string	✓	The title of the book.
`description`	text	—	A description or summary of the book.
