List of proofreader's marks
From Wikipedia, the free encyclopedia
This article is a list of standard proofreader's marks used to indicate and correct problems in a text. The marks may be abstract symbols, abbreviations, or (in some cases) entire spelled-out words. These are usually handwritten on the paper containing the text. These indicators are interleaved in the text or placed in margins.[1] Different languages use different proofreading marks and sometimes publishers have their own in-house proofreading marks.
Lists of these marks can often be found in relevant standards like ISO 5776 or BS 5261, style guides such as The Chicago Manual of Style,[2] encyclopedias such as the Encyclopædia Britannica,[3] dictionaries such as the OED,[citation needed] and instructive materials for editors and proofreaders.

| wf | Wrong font | Put text in correct font |
| ww[4] | Wrong word | Wrong word used (e.g. to/too) |
Symbols

Most, but not all, of these symbols can be found in The Chicago Manual of Style.[2] If Unicode contains a character that can be confidently identified with the symbol, its codepoint will be listed; otherwise the symbol in the symbol column is either an image, an html creation, or a typographical approximation using a similar unicode symbol.

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.[8][9]
The more common conventions are these:
- single dashed underline for stet, 'let it stand', proof-reading mark cancelled. The margin note
stet /may be added. - single straight underline for italic type
- single wavy underline for bold type
- double straight underline for small caps
- 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).
