As an author, there are three basic broad-heads of editing services available to you:
Copy Editing : This service is suitable for quality-conscious authors requiring a thorough language check of their manuscripts. Papers submitted to the Copy editing service are returned free from language errors such as spelling mistakes, grammar, punctuation errors, and typos. Authors also get a style and consistency-check done on their manuscripts, in addition to having them formatted.
Substantive Editing : Authors looking to submit their manuscripts to high-impact peer-reviewed international journals can opt for Substantive editing. This service offers intensive research editing services for the authors to achieve flawless subject-matter and language quality. Substantive editing covers all service aspects under Copy editing, including a deep focus on the logic, structure, and presentation of the manuscript.
Proofreading : Proofreading is done after editing and layout, after the page proofs have been prepared by the designer. While Copy editing errors may still be found, a proofreader is concerned with other elements. The proofreader checks all design elements for accuracy and consistency including headers, level heads, page numbering, word breaks, end-of-line breaks, page breaks, cross references, and appropriate placement of tables and artwork. Proofreading service may also include completion of table of contents, index and numbering of cross references.
