Frequently asked questions
Which books can I add?
Search Rakuten Books or Open Library by title or author, then choose an edition with a cover and ISBN. You can filter for Japanese or English books.
Do I need an account?
You can create, save, and share a shelf without an account.
Can I close the page before finishing?
Unsaved books and inputs are stored automatically in this browser. Return to the home page in the same browser to continue. The draft is removed after your shelf is saved publicly. Drafts cannot be restored if browser data is cleared or local storage is unavailable.
Who can see a saved collection?
Saved collections are public. Anyone can view them via their shared URL or Community shelves.
Can I edit a saved collection?
Saved collections cannot currently be edited. To make changes, create a new collection from the home page.
What if I cannot find or load a book?
Try another title, author, or language filter. Books missing from the catalog and editions without a cover or ISBN are not shown. For connection errors, try again later.
