Proof-reading
Proof-reading incorporates checking the grammar of a text, also correcting the spelling, punctuation and the construction of sentences.
Editorial Service
The editorial service always includes the proof-reading, but goes far beyond this. The editorial service does not only include the correction of grammar but also looks at the style, construction, logic, and the causal relationship and conclusiveness of each text. The editorial service is therefore the ultimate place to look at those points that render a text coherent and round it off.
