A proofreader receives the proof after it has been designed, edited and typeset, correcting text and layout. I have been trained in the use of standard proofreading symbols for typesetters, but I can also use more familiar annotations if these symbols are not personally recognised. Many clients nowadays prefer to send artwork as a PDF file which has an editing facility, or as a word document using 'track changes' editing.

My proofreading service includes: 

• reading for sense
• checking spelling and grammar
• correcting other typographical errors
• noting inconsistencies of style and format
• checking textual presentation
• drawing the editor's attention to any other issues.

A good proofreader is always aware of the author's chosen style and 'voice', and a close read will identify any inconsistencies which might have been missed through re-writes or revisions before going to print. Errors found at the print stage are costly.

I use the Oxford English Dictionary for corrections, unless otherwise specified.
