As noted in the
Short Stories main (periodical) entry, a mistake in the magazine's whole numbering occurred in 1948 when the 25 December jumped from 1029 to 1930 - an increase of 900. This mistake was never corrected. As
Galactic Central notes, the correct number of issues over the magazines lifetime was 1114 (not 2014). The whole number given to the February 1950 issue was 1946. It should have been 1046.
