The book of crown lore

The librarian Keldriel says she has found, deep in the Library of Madness, a book containing the lore of crown forging BK E1·01:07:01. She calls it the journal of the Lord of Shadows and says its spells may hold clues to finding his last crown BK E1·01:07:14. Later she uses mage hand to hand the book of crown lore to Efink's group BK E1·01:56:02.

The book of crown lore is the book Keldriel finds in the Library of Madness, which she calls the journal of the Lord of Shadows BK E1·01:07:01 BK E1·01:07:14.
