How do I determine what file type a book is in Apple Books?

How can I determine what format a document in Apple Books on iPad is using? I googled it and the AI result says to tap the ellipsis of a book title and select Get Info to see the doc type. However there is no Get Info option. Is there another way? iTunes?

I have a book I downloaded and trying to determine if it’s a PDF or eBook.

Thanks,

Terry
