The author has written in the correct format and in a language style reasonably consistent with native English usage. Thus the editor only has to edit to ensure overall clarity and sense for improved readability. Copyediting includes any or all of the following:

• The editor will have corrected spelling (ensuring consistency of British or US spelling), grammar, punctuation, syntax, and word usage while preserving the meaning and voice of the original text.
• The editor will have edited to keep to conventions regarding use of numbers, italics etc.
• The editor will have cross-checked that references, figures, tables, etc are consistent with their mention in the text.
• Checked for and pointed out any apparent errors or inconsistencies of facts.
