In almost all cultures and societies, children have collected a broad spectrum of items. Although the activity seems to be universal, very little has been written on this subject. And even though collecting has played an important part in many individuals’ lives, it is seldom described in memoirs or autobiographies. This may be because many collections are suddenly abandoned when the collector grows up. Many are often split up and disappear during childhood unless parents understand the fascinating world of the small collector and pay special attention to saving them. Other collections, however, continue into adult life, becoming lifelong passionate occupations; this is especially likely with collections that have some kind of economic value or present the adult with challenges or opportunities for further study.
