Hello! Is there a way to make a quarto book citeable? The Quarto documentation, Quarto - Creating Citeable Articles, would seem to indicate that this is possible for articles but it does not seem to work for books.

In case it's helpful, my book is here, Multilevel Thinking, and my YAML is here, multilevel-thinking/_quarto.yml at main · agrogan1/multilevel-thinking · GitHub.

Thank you for any help you can provide.

Summary: consider adding by default to the title page, or by targeting a div with a particular id.
