CTC will ask for your work to be submitted electronically as a Word Document. It is edited and/or proofread using the 'Track Changes' format so that all changes or comments are visible, then returned to you: it is your call to accept or reject the suggestions.
This file is a sample of what the document looks like. You can see where changes are made, they are enbedded (in red) within the text itself and also annotated in the right margins.
We work together until you are satisfied. Once the final version is accepted, CTC inserts it into a master document for formatting as 'publisher-ready'.
