Book of Salvation
From Warhammer 40k - Lexicanum
The Book of Salvation is a revered tome of the Dark Angels.
Never leaving the side of the Chapter's Chief Librarian (currently Ezekiel), the book contains the names of those Fallen that have been captured, often using their own blood as ink. The book is carried by the Chief Librarian until his death, when it is passed to his successor.
