Editing Point (typography) (section)

===Old English points===
Although the English Monotype manuals used 1 pica = {{convert|0.1660|inch|mm}}, their manuals used on the European continent use another definition. There, 1 pica = {{cvt|0.1667|inch|mm}}, the Old English pica. As a consequence all the tables of measurements in the German, Dutch, French, Polish and all other manuals elsewhere on the European continent for the composition caster and the super-caster are different in quite some details. The Monotype wedges used at the European continent are marked with an extra 'E' behind the set-size: for instance: 5-12E, 1331-15E etc. When working with the E-wedges in the larger sizes, the differences will increase even more.<ref>{{cite book |first=Rich |last=Hopkins |title=Origin of the American Point system for Printers |chapter=Type Measurement |publisher=Hill & Dale |location=Terra Alta, West Virginia |orig-date=1976 |date=1989 |oclc=2524743}}</ref>
