List of proofreader's marks explained

This article is a list of standard proofreader's marks used to indicate and correct problems in a text. Marks come in two varieties, abbreviations and abstract symbols. These are usually handwritten on the paper containing the text. Symbols are interleaved in the text, while abbreviations may be placed in a margin with an arrow pointing to the problematic text. Different languages use different proofreading marks and sometimes publishers have their own in-house proofreading marks.[1]

These abbreviations are those prescribed by the Chicago Manual of Style.[2] Other conventions exist.

Manuscripts

Depending on local conventions, selected text may be underscored (underlined) to indicate any special formatting or typeface to be used, with an explanatory abbreviation written in the margin.[4] [5]

The more common conventions are these:

  • single dashed underline for Latin: stet, 'let it stand', proof-reading mark cancelled. The margin note may be added.
  • single straight underline for italic type
  • single wavy underline for bold type
  • double straight underline for
  • double underline of one straight line and one wavy line for bold italic
  • triple underline for FULL CAPITAL LETTERS (used among small caps or to change text already typed as lower case).
