proofreading

proofreading, reading and marking corrections on a proof (the copy of a text that is submitted for correction) or other copy of the text of articles and books before publication. It is the final stage of the editing process, preceded by prewriting, planning, writing a first draft, revising, and editing. The goal of this stage is to remove surface errors such as incorrect formatting, spacing, punctuation, grammar, and spelling.

Traditional proofreading

Proofreading dates from the early days of printing. A contract of 1499 held the author finally responsible for correction of proofs. In modern practice, proofs are made first from a galley, a long tray holding a column of type, and hence are called galley proofs; the term is sometimes also used for the first copy produced in photocomposition (a process of setting text by projecting characters onto photographic film or paper, replacing traditional metal type) and other forms of typesetting (the arrangement of text for printing, whether by hand, mechanical type, or digital means) that do not involve metal type.

Galley proofs, and the later proofs of the type arranged into page form, usually bear queries (regarding possible errors of fact) arising through the proofreader’s skill, which involves more than assuring an exact correspondence between the copy given to the printer and its printed form. Lawsuits between printers and authors, errata sheets (lists of corrections), authors’ apologies and complaints at not seeing proof in printed books, all were common through the 15th, 16th, 17th, and 18th centuries; and even in modern publication they are not unknown.

Many proofreading marks (see illustration for the use of some of the most common ones) are also used in editing copy before the proof stage.

Digital proofreading

Digital proofreading is the process of identifying and correcting errors in electronic documents using software solutions before publication. Unlike traditional proofreading, which often relies on printed proofs and manual marks, digital proofreading methods include using word processing tools with built-in spellcheck, grammar check, and the Track Changes feature.

Many professionals now rely on PDF editors and online platforms to annotate and share changes on page layouts. AI-powered tools might help spot grammar, punctuation, and formatting errors but still require human oversight for context and nuance.
