Once upon a time, editors requested submissions in single-column, double-spaced form because they (or the in-house writers) would actually mark on the printed-out paper. Mysterious glyphs, squiggly arrows, and indecipherable handwritten text would be inscribed between the lines in red ink. Many journal preprints from that era are double-spaced.

Even more mysterious are the arcane notations such as “TABLE 1 ABOUT HERE” with the actual table/figure contents placed at the end of the paper. Understandable when authors provided hardcopy figures for photoreproduction, baffling when the entire submission was generated with LaTeX or Word.
