In NetHack, the spellbook of cancellation allows you to learn the cancellation spell.

Effects
Main article: Cancellation
When cast, the spell of it fires a beam which works exactly like the wand of cancellation: items will be uncursed and unenchanted, scrolls and most spellbooks will be blanked, most wands and magical tools lose their charges, and most potions will be turned into water. Monsters hit by the spell must each pass a monster MR check; if they fail, they can lose a lot or all of their special attacks.
The spellbook of cancellation is the only book that cannot be cancelled into a spellbook of blank paper by the spell or wand of cancellation, and the spell also cannot cancel the wand of cancellation or the wand of nothing.

Strategy
The spell is very difficult to cast and of questionable utility - finger of death can kill most monsters outright for the same cost in magic power. Zapping a wand of cancellation will suffice for most situations, possessing the same benefits and drawbacks without the high magic power requirement. However, the spell has some benefits over the wand: a spellbook does not require special care around a bag of holding like the wand of cancellation, and at higher experience levels, the spell has a significant advantage in successfully passing monster magic resistance checks.
