7. The Genocide Machine
The library on Kar-Charrat is one of the wonders of the Universe. It is also hidden from all but a few select species. The Doctor and Ace discover that the librarians have found a new way of storing data - a wetworks facility - but the machine has attracted unwanted attention, and the Doctor soon finds himself pitted against his oldest and deadliest enemies - the Daleks!
