Much of the White Tower Library was saved when the Dreadlords and the Black Ajah destroyed the Tower. The Aes Sedai and the Asha'man had gotten word of the invasions beforehand and thus was able to save much of what was and was able to evacuate the City.
As such, this Library is still foremost in the world.
For Novices, there is a ter'angreal that leads to and from the White Tower. Its frame is white and leads to the Front Hall. For Soldiers, there is also a ter'angreal that leads to and from the Front Hall of the Black Tower.
