Holodiary

"Oh, I have no illusions about the fact that my escape was a result of the highly sensitive knowledge that I possess: a holodiary cataloging the nefarious deeds of this council."

- Ziro to the Hutt Council

A holodiary was a type of datapad that was used for information storage. During the Clone Wars, the Hutt Ruling Council contained its criminal dealings on a holodiary that eventually fell into the possession of the Hutt Crime lord Ziro.
