Proofreading traditionally means reading a proof copy of a text in order to detect and correct any errors. Modern proofreading often requires reading copy at earlier stages as well.

Proofreading in printing and publishing

A proof copy is a version of a manuscript that has been typeset after copy-editing. Proof typescripts often contain typographical errors introduced by mistyping (hence the word typo to refer to misplaced, missing or incorrect characters). Traditionally, a proofreader checks the typeset copy and marks any errors using standard proof correction marks (such as those specified in style manuals, by house style, or, more broadly, by the international standard ISO 5776, or, for English, the British Standard BS-5261:2). This process may be known as a line edit. The proof is then returned to the typesetter for correction, and in many cases the production of a second proof copy (often known as a revise). Proofreading is considered a specific skill that must be learned because it is in the nature of the mind to correct errors automatically. Someone not trained in proofreading may not see errors such as missing words or improper usage because their mind is showing them what it is trained to recognize as correct.

The term proofreading is sometimes used incorrectly to refer to copy-editing. This is a separate activity, although there is some overlap between the two. Proofreading consists of reviewing any text, either hard copy on paper or electronic copy on a computer, and checking for typos and formatting errors. This may be done either against an original document or "blind" (without checking against any other source). Many modern proofreaders are also required to take on some light copy-editing duties, such as checking for grammar and consistency issues.

Proofreading in biology

The term proofreading is also used to refer to the error-correcting processes involved in DNA replication. In bacteria, all three DNA polymerases (I, II, and III) have the ability to proofread, using 3'->5' exonuclease activity. In eukaryotes only the polymerases that deal with the elongation (?, ? and ?) have proofreading ability (3'->5' exonuclease activity).
