Registering DOIs at the chapter level increases discoverability by providing a unique, persistent identifier for each part of a book. This allows for individual chapters to be cited, tracked, and linked to other content online, supporting discoverability, usage tracking, and reference linking between chapters and other scholarly works like articles. It also gives authors greater visibility and helps publishers track performance and manage content.
