The majority of A-Z maps are orientated with north at the top of the sheet or page. However, this publication attempted to address an issue where some people had trouble flipping the map in their minds when travelling south down the page, often resorting to turning the book upside down. This 1993 A-Z Coming and Going Road Atlas has a standard set of north-top pages and a set of south-top pages (as the Liverpool and the Llyn Peninsula example here). Before computers it would have been necessary to lay out a second type sheet by hand for the different orientation, a time consuming exercise. However, computer software made the task much simpler and of course quicker to do.
