All the Weyrs of Pern

When AIVAS - the Artificial Intelligence Voice Address System - was first discovered at Landing, the entire planet of Pern was awed at the knowledge it divulged. All the history of the peole of Pern was there. Dragonholders, Lord Holders and Craftmasters crowded into the tiny inner room to learn the secrets of their beginnings. And AIVAS had other gifts to offer - stored information of old crafts that had been forgotten, or medicine, music and technology.
