Go
spiritual. That's the only way I know to handle anger.
Our temper is govern by the state of Mars in our natal chart.
Everyone has different degree of temper because we all have
different placing of Mars. When Mars is afflicted (especially by
Signs of Aries and Scorpio), our animalistic instinct tends to blow
out of control and subjected to the tendency of inflicting 'damage'
on things/people to mollify our moods.
Human is but a higher being with a conscious mind. When you loses
your conscious self, what's left is the rudimentary animal self
that is common to all beings in the animal kingdom.
Then you become an animal.
Damaging your book is nothing - what's worst is when you hurt
someone with your temper so badly that the wounds become permanent.
You can always buy a new book another day, but you can never piece
back a shattered relationship.
I recalled an old case in Aunt Agony, where this guy lost the woman
he loved because of his foul temper. His realization only came when
he lost her forever. Albeit he vowed to correct his flaws, by going
through anger management course and stuff, it's too late to save
his relationship, although it's never too late to save
himself.
Do you need be like him before you truly evolve?
Go spiritual. Seek advice from your religious leader if you need
to. I would also suggest you drop by Borders and purchase a book on
anger management. 
Cheers
