Pratchett Terry. Discworld 22. The Last Continent

Something is seriously amiss at Unseen University, Ankh-Morpork's most prestigious institution of higher learning.A professor is missing-and not just any professor. The Egregious Professor of Cruel and Unusual Geography. Also the University Librarian, who transmuted (you know how things change!) into an ape (a handy configuration for a librarian, don't you think?) so long ago that no one exactly remembers his name, least of all himself.But fear not, the search is on! The Lecturer in Recent Runes and the Chair of Indefinite Studies, as well as the Dean and the Archchancellor, will follow the trail wherever it leads-even to the other side of Discworld, where the Last Continent, Fourecks, is under construction.
