The book just isn't for show. It holds detailed reports of a number of battles, information about the types of soil various places have, and other such valuable information. It also shoots out magic, which a lot of people don't expect. Taking advantage of that will restore your Focus Points based on Rank when you hit an enemy with a Tome weapon attack. The bonus is also increased based on your Tactics Rank.
