Expulso spellbook

The Expulso spellbook is a book containing information on and instructions how to perform the Expulso Curse. It was owned (possibly stole or confiscated) by Dolores Umbridge in 1997 and was lying on her desk at her office, which she owned as Head of the Muggle-Born Registration Commission and Senior Undersecretary to the Minister for Magic at the Ministry of Magic. When Harry Potter came by it during the Infiltration of the Ministry of Magic he picked it up and learned the spell.
