I just used the latest Stat Abs, (the print was received in late Jan. 2005) and discovered that
for the first time, it covers a two year publication cycle, 2004-2005.
According to explanatory materials, the cutoff date is for data available by summer 2004.
It will go back to covering only 1 year in 2006. The change was instituted "so that the year in which most of the sales occur will be reflected in the title," a practice held by many private
almanacs and yearbooks.....
