A repository of knowledge existed on the planetary body known as Primus Cabru. The aforementioned library was infiltrated in 21 ABY by Ochi, a Sith assassin, who absconded with the information-holding D-O following the assassin's fatal slaying of the scholar who was the droid's owner.
The 2022 book Shadow of the Sith, penned by Adam Christopher, referenced the repository.
