Projects occasionally require researchers to explore the history of an organization. This may involve using earlier editions of the Yearbook.
Over time the Yearbook has made editorial adjustments in response to changes in classification standards, geopolitical challenges, as well as the success or failure of an international association. For details on how the Yearbook has responded to these changes see the section titled: Continuity Between Editions (Also in: Vol. 5, 2010/11 edition, starting on page 15).
