Book metadata refers to the information that describes a book and helps categorize it for readers and retailers. This includes details such as the title, author, publication date, genre, and ISBN number. Metadata is essential for libraries, bookstores, and online platforms to organize and manage their collections effectively. Additionally, book metadata can include descriptions, keywords, and cover images, which enhance discoverability. Properly formatted metadata ensures that readers can find books easily through search engines and online catalogs. It plays a crucial role in the publishing industry by improving visibility and sales potential for authors and publishers.
