In addition to developmental editing and many other services, I currently offer two levels of line editing (also called copyediting or CE).
Copy (line) editing, light includes correcting spelling, grammar, punctuation, syntax, and word usage; checking for or imposing a consistent style and format.
Copy (line) editing, heavy includes correcting spelling, grammar, punctuation, syntax, and word usage; minor fact-checking; checking for or imposing a consistent style and format; suggestions about paragraph length, breaking or joining sections; preparing a style sheet if required; querying author as necessary during the process.
With the author’s permission (personal details have been deleted and various character/product names changed) I’ve posted PDFs of these samples below:
Of course, every piece of writing is different, and every bit of editing is tailored to your needs. These samples should give you a better idea of the difference between simple and heavy copy edits, though. If you have any questions, please feel free to post them below, or contact me here.
