Structural editing 

Structural editing is a comprehensive revision of the structure of text, improving the clarity, legibility and purpose of the text:

+ ensuring the content, organisation, plot, themes, voice, tone and pace of text are consistent
+ checking for content discrepancies.

Copyediting

Copyediting is a detailed review of text, undertaken at final draft stage, ensuring text is readable, clear, consistent, and meets professional style standards:

+ correcting spelling, grammar and punctuation
+ correcting inappropriate, ambiguous or incorrect statements
+ ensuring a consistent writing style
+ checking the application of a style guide
+ checking cross-references within the text
+ ensuring previews, summaries, and end-of-chapter questions reflect content.

Proofreading

Proofreading is a quality assurance check undertaken once text is finalised. This final stage of editing picks up small anomalies and errors in text, ensuring it is ready for publication:

+ correcting spelling, grammar and punctuation
+ checking for typographic and other anomalies.
