Hi!
I have a question regarding registering DOIs for a new, extended publication of a book. The first version of the book (2022) has a DOI assigned at Book Title level and 10 chapters with unique DOIs, already registered. The new book (2024) will be published with a new ISBN and it’ll contain two extra, new chapters compared to the first version, but the other 10 chapters won’t be altered in any significant way between publications.
What’d be the best practice in this case? Should we reuse the old DOIs in this case for the older, unchanged chapters, even if it means resubmitting/changing the associated metadata (there might be changes in page ordering), or should we handle them as completely separate entities and assign new DOIs to them?
Are the changes substantial enough for the extended edition and chapters to get their own separate DOIs?
Thank you for the help!
