These dolls are placed into year of release based on guidebooks and other research, starting with the Superstar era (1977). Unfortunately, the release year does not always correspond with the copyright year printed on the box. Whenever possible, we have put all pertinent dates in the title of the doll, but each doll will only show up once in the menus. If you are having trouble locating a doll by year, check in the surrounding years as there may be a discrepancy.
