Books are a means of storing information as text or images. Modern books typically take the form of a codex, consisting of numerous bound pages within a protective cover. Prior to the codex, books existed in forms such as scrolls and tablets. The creation and distribution of books involves a series of steps known as the book publishing process.
In 1900, book printing methods remained largely unchanged since the 15th century, relying on movable metal type. Modern paper books began using specifically designed paper, with varying qualities for different book types.
By 1970, the ISBN system was in place, providing unique identifiers for books, as a result of increasing organization and classification strategies from libraries and library professionals.
In 1997, standards like ANSI/NISO Z39.41 – 1997 were implemented to standardize the placement of information (title, author's name) on book spines and similar objects like DVD or software containers. While ISBNs became common, some government publishers did not participate, highlighting exceptions in the seemingly international system.
In 2010, the book industry experienced significant changes with the rise of new technologies like ebooks and audiobooks, catering to a wider audience and increasing accessibility. Google estimated 130 million unique books published by this time.
In 2011, the International Federation of Library Associations and Institutions (IFLA) established the ISBD to standardize bibliographic descriptions. The ISBN system, with its unique identifiers and four-part structure (country code, publisher code, title code, and check digit), became internationally managed.
By 2021, the English-language publishing market was dominated by the "Big Five" publishers: Penguin Random House, Hachette Book Group, HarperCollins, Simon & Schuster, and Macmillan Publishers, controlling nearly 60% of the market for general-readership books.
