If you’re adding in backlist records manually, the process is almost the same as adding new ones.
1. Follow the instructions to add a new work
Find them at ‘Add a new work, its contract and its products’.
2. Choose a 'placeholder’ ISBN
The only difference is that you already know the ISBN13. However, you don’t manually fill in ISBN13s on this page. Choose ‘placeholder’ instead.
3. Edit the ISBN13
After you’ve saved the page, go to Work > Metadata and find the ISBN section (Publication > Identifiers). Type in your ISBN13 and click Save.
