Bingo Book

The is a book containing any and all information on every missing-nin that all Jonin and members of ANBU of the major shinobi villages are given by their respective Kage to hunt down and assassinate. The purpose of this is so the village's secrets and/or kekkei genkai aren't stolen or examined by the enemy. Kirigakure no sato has a special unit within their ANBU called hunter-nin whose sole purpose is the complete eradication of these missing-nin.

There are many versions of the Bingo Book besides those distributed in the shinobi villages. Akatsuki uses a Bingo Book that, instead of listing Missing-nin, provides information on the hosts of tailed beasts (which must be captured alive) and those shinobi that are known as the most powerful assets to a certain Village. Kakuzu makes use of this addition to track down shinobi in the hopes of gaining their bounties. (Such as when he attempted to kill Asuma for his 35 million ryō bounty.)

Trivia

 * Although the word for Bingo Book is written in kanji (手配書), it's pronounced in English ("Bingo Book"). The Japanese pronunciation of the kanji would be "tehaisho," which would literally translate to "book of search instruction," as in, the instruction and protocols used for police searches and arrests.
