? As we all know, ISBN plays an important role in book publishing. A book must have a book number when it should have one, and it must be changed when it should be changed. A book published after revision is called a revised edition. The publication of the revised edition of the book is also of great significance. Generally, a book will be published after modifying the original because of cultural inheritance, adapting to the changes of the times and errata. As for whether a book will change its book number after publication, it is related to the change of the content size of the revised book.
The publication of the revised edition shows that the contents of the original book have been revised. When the revised content is basically unchanged, the book will be published after revision, and the original book number will be adopted. However, the revised version of this book will generally add an additional code after the book number, which should be filed with the General Administration of Press and Publication. If the content changes greatly, the revised book is equivalent to a new book, and the book number needs to be changed if it is published again. There is no specific regulation on how much or how little the revised content changes. The general ratio is 30%. In other words, after a book is revised, 30% of the contents in the book will change, and the book number will change when it is published, and vice versa.
If a book is published after revision and meets the standard of ISBN change, the author should try to re-apply for the application number and find out how to charge the current application number. When the revised book is suitable for self-funded publication, the author needs to pay the ISBN management fee.
