The History of the Greater and the Lesser Houses

"Girl. Fetch me The History of the Greater and the Lesser Houses."

- Tywin Lannister to Arya Stark

The History of the Greater and the Lesser Houses is a book detailing the history of several noble houses of the Seven Kingdoms of Westeros.

Season 2
Tywin Lannister is in possession of a copy of the book. During his occupation of Harrenhal he keeps it in his war council chamber. When due to Ser Amory Lorch's nigh-illiteracy a letter detailing Western infantry movements is sent to Lord Marlin Dormund, a vassal of House Stark, instead of Lord Damon Marbrand, a Lannister vassal, Lord Tywin orders his cupbearer, Arya Stark, to fetch the book. Arya finds it before he tells her which one is it. Tywin then uses the book to remind Ser Amory that the Dormunds are Stark vassals.
