Books are Dead Rising items which increase Frank's abilities in different ways, so long as they are in his inventory. The Willamette Parkview Mall has five bookstores, which have 24 books in total. Most books affect the durability of a group of weapons. For example, the Engineering book affects the sledgehammer, sickle, hedge trimmers, etc. Many of the books that have effects other than making weapons last longer are rewards for killing certain psychopaths.
