Anatomy of a Typeface:
fonts and typefaces were two different things — the typeface was the specific design of the letters, say Times New Roman or Baskerville; while the font referred to the particular size or style of that typeface, say 10 point regular or 24 point italic (each created as its own collection of cast metal letters and other characters).
