Proofreading/Editing

Proofreading is the process that involves examination of the document to check grammar, syntax and spelling, and lack of consistency in the text style like fonts, highlights like bold and italics, spacing, underscore, etc., and it ensures the document is entirely free of errors and polished to a high standard. 

Editing implies looking at the document as a whole and checking that it has been put together in the best possible way. Editing can involve checking facts to ensure that information included in a text is accurate and checking that the text does not have any fundamental inconsistencies. The process includes research and often involves several revisions of the text and may require that portions of the document are removed, changed or that more text is added to make communication clearer.

 Editing/proofreading is performed by experienced linguists and it is strongly recommended for all texts intended for publishing and public use.
