Annotated Directory of Streets, Alleys, Roads Lanes and Yards of Ankh-Morpork
This is the indispensible Aye too Zedde allowing the walker or casual visitor to know exactly where they are or need to get to in Ankh-Morpork in a matter of seconds. It is published as an integral part of The Compleat Ankh-Morpork and accompanies both the revised and new City map and the far more detailed map of the Shades contained therein.
Of course, anyone seen consulting a street map whilst actually in the Shades is immediately identifying himself as a tourist (pronounced mark) and a visitor (pronounced target). Focusing your attention entirely on a street-map and letting awareness of your immediate environment lapse might also be considered a form of suicide by the Watch. Streets are located by an alphanumeric grid, and streets in the Shades are doubly indexed according to which map you are consulting. (however briefly).
