This is why you need The Writing Shed.
Proofreading is the final check before a document is ready for publication or submission to your University. You should provide your copyedited copy so a comparison can be made to ensure all suggestions have been included in your final copy. Proofreading will check for typographical errors, spelling, punctuation, formatting and layout. References and electronic links can be spot-checked if requested. Proofreading is a quality control exercise to ensure all changes in your copyedited edition are included in your final document. Proofreading is not copyediting.
Copyediting will check for grammar and wording, paragraph and sentence structure, relevance to subject matter, and that your written meaning is clear. Copyediting ensures that there is a consistent approach to terminology, spelling, capitalisation and the document is visually consistent. Spot-checks on the accuracy of the cross referencing and links within the document are done and reference lists and bibliographic references are checked for completeness and consistency.
Substantive or Structural editing (please note this service is not available to students)
Substantive editing involves a wide range of tasks. Documents are checked for conceptual integrity, language, style editing, clarity of presentation and usability.
