This appendix lists all the science-fiction magazines covered by this volume together with issue and editorial details. It also covers strongly associational titles. Magazine titles are listed in alphabetical order of first issue. Individual issues are listed for each year together with a cumulative total at the end of each column (in brackets). Dates shown are cover dates. The cut-off date for this volume is December 1950, though magazines which folded in 1951 are shown to their final issue. Magazines continuing beyond that date are covered in Volume II. Combined months are shown thus: May/Jun means a single issue with the cover date May/June. Months are abbreviated to their first three characters. Seasonal dates are shown thus: Spr = Spring; Sum = Summer; Aut or Fall = Autumn or Fall; Win = Winter. Seasonal issues and undated issues are shown in the column corresponding to the month of sale. Reprint editions are not listed unless their contents vary significantly.
