# Duplicate Book

To duplicate the book that you have created, follow these steps:

1. Click the book menu in the book header and select "Duplicate Book".
2. When duplication is completed, the new book will be displayed with the book name "XXX (Copied)". Likewise, the navigation menu will also display new entry of "XXX (Copied)" for the newly duplicated book.

For a book where the user has only view-level access, if the "Duplicate Book" operation in "Allowed Operations to Other Users" is not permitted in the book setting, the "Duplicate Book" menu cannot be selected. For details about book access permissions, see "[Book Access Permission](/mashmatrix-sheet/functions_about_books_sheets/manage_book_access_level.md)".
