<p data-pm-slice="1 1 []">Planning to publish a book independently or through a publishing business? ISBN registration helps identify a specific book edition and supports its cataloguing, distribution, and discoverability. Authors, publishers, and eligible self-publishers should review the applicable ISBN guidelines and prepare accurate details about the book, its title, author, publisher, and publication format. Providing complete information can help reduce application errors and support a smoother process. Agile Regulatory offers guidance with publication-related documentation and application procedures to help applicants understand the requirements for ISBN registration.
