Introduction

In principle, a school atlas presents a status quo at a given moment, although by doing so it links thousands of stories: countries that achieved their independence, railways completed against all odds, or river valleys whose population was displaced in order to allow for the construction of reservoirs. Sometimes, it may contain references to single events, like a flood or a wildfire that happened at a specific point in time, but as they detract from the main purpose of a school atlas, i.e. to show long-term developments and durable situations, such remarks on the map are short-lived, and seldom survive the next edition. The map detail in Figure 32, taken from the 1921 edition of the Bosatlas, a famous school atlas edited and used in the Netherlands, offers a comment on the collapse of a river dyke following the flooding of the Meuse River in January 1920 (Doorbraak Jan. 1920). This event caused the town of Kuik (Cuyk) to be inundated. This comment was dropped again in the next edition.

When a school atlas is regarded as a serial work that is annually or biannually updated, and when, thanks to digital technologies, the same maps in consecutive atlas editions can be compared one to another, then we are mapping movement through the times.
