Turtle Recall. The Discworld Companion… So Far: Pratchett, Briggs

The Discworld, as everyone knows, is a flat world balanced on the
backs of four elephants which, in turn, stand on the shell of the giant star turtle, the Great ATuin, as it slowly swims through space.
It is also a global publishing phenomenon with sales of about 75 million books worldwide. The publication of Snuff brought the Discworld canon to 39 books - not including the various guides, maps, diaries and other side-projects. That's a lot of Discworld to keep track of - more than most people can manage with just the one head - but fear not: help is at hand!
If you're looking for the ultimate authority on probably the
most heavily populated - certainly the most hilarious - setting
in fantasy literature...
If you need a handy guide to Discworld locales from Ankh-Morpork
to Zemphis...
If you want help telling Achmed the Mad from Jack Zweiblumen...
If your life depends on being able to distinguish the Agatean Empire
from the Zoons...
... look no further than Turtle Recall: The Discworld Companion... so far - now fully updated and completely up to Snuff!
