Jedi Archives The Jedi Archives was the Jedi Order ' s repository of knowledge on Coruscant , rumored to hold the sum total of all galactic knowledge . The Archives were overseen by the Council of First Knowledge . History . Established in the Jedi Temple on Coruscant by the Jedi Order early in the Temple ' s history , the Archives held the remnants of the texts once stored in the Great Jedi Library of Ossus . The Archives contained historical records dating back thousands of years ; maps of the entire galaxy ; scientific , mathematical and astronomical journals ; engineer ing and technology documents ; and Jedi records on the Sith . It detailed the geography and cultures of various planet s and species across the galaxy , as well as their zoology and botany . Secrets about how the Jedi used the Force and biographies of numerous Jedi and their identification details were also housed in the Archives . Built near the top of the Temple Ziggurat , the Archives was a two - story cruciform chamber centered around a large rotunda . Four wings branched out from the rotunda and held tens of millions of books . The central reference desk was located at the heart of the Archives . The Chief Librarian , assisted by associate librarians and JN - 66 and SP - 4 analysis droids , administered the Archives . During the Clone Wars , it was overseen by Jocasta Nu , who assisted Jedi in finding the information they needed and also controlled access to the restricted Holocron Vault within the library . Before the Battle of Geonosis , Jedi Knight Obi - Wan Kenobi tried to find information on the planet Kamino to find the bounty hunter Jango Fett . He and Nu discovered that there was no information on the system . Kenobi and Yoda deduced that a Jedi had erased the information on Kamino . After the rise of the Galactic Empire , Emperor Palpatine allowed the Grand Inquisitor to study the records about the Jedi and their combat forms . It was at this time Nu , who survived the fall of the Temple , returned to the Temple . Unnoticed by the Grand Inquisitor , Nu entered a secret vault within the Archives , where she retrieved a list of every known Force - sensitive children , as of just before the purge . Though intent on leaving without conflict , upon sighting the Inquisitor again , Nu accosted him with her lightsaber , offended that he dared to read her book s only to toss them aside . After a brief lightsaber duel however Nu was bested , but as the Inquisitor prepared to deliver the final blow , he was interrupted by Darth Vader ' s blocking saber . On orders from Emperor Palpatine , Vader demanded her alive . In the verbal confrontation that followed , Nu Force push ed the two and fled . Retreating to a computer in the library , Nu subsequently purged all the archive files . As Vader continued his pursuit , Nu retrieved a weapon stored in the archives that was capable of fighting Vader . Later , the Emperor converted the Temple into his Palace . The Imperial Security Bureau took control of the remaining secrets within the Archives , removing all Jedi - related material and destroying much of their history in the process within a year of the library ' s seizure . Behind the scenes . According to Pablo Helman , during the scene where Obi - Wan Kenobi speaks to Jocasta Nu , the room includes busts of himself , George Lucas , Rob Coleman , and John Knoll .
