A man was one of 4,022 people saved in the Library Data Core in the 50th century after the Vashta Nerada attacked and there was nowhere safe for the computer to teleport them to. In 51st century, after the Tenth Doctor was given extra time by the Vashta Nerada, River Song sacrificed herself in the Doctor's place to bring the Library's visitors out of the Core and to stop the Library's auto destruct by using her brain to give the Library extra memory space. Disoriented, the man asked Strackman Lux how he had got to where he was. Mr Lux celebrated that the man, and all the visitors, had come back. (TV: Forest of the Dead)
