Jedi Archives/Legends
After the world of Ossus was devastated in 3996 BBY and the Great Jedi Library was destroyed, the Jedi fled their long time home, taking with them what they could of Jedi Master Odan-Urr's great collection.[1] Fleeing across the galaxy, the Jedi met at Exis Station, gathering to them what they could from Ossus.[2] Following the conclave, the Jedi largely relocated to Coruscant, in the Jedi Temple constructed by four Jedi Masters.[3] The ever-growing Temple's original incarnation of the library was located several stories above the main entrance of the Temple, serving as Archives and library for several centuries.
Behind the scenes
There is no indication of a specific location named the Jedi Archives in Canon, especially not in the 'Jedi Temple' or maintained by the 'Jedi Council' as those are prequel concepts. The term though is mentioned in various Tales of the Jedi sources, and this article needs to be rewritten as a brand new one to reflect that stuff.
