I have just started perusing The Craft of Editing by Michael Alley, which is subtitled A guide for managers, scientists, and engineers. Right near the start three different types of editing are highlighted, editing for content, editing for style and editing for form. However, the most important thing emphasized at this point is that whilst a lot of time might be spent discussing editing for style or form, these are relatively unimportant compared with editing for content.
Editing for content is defined as ensuring that the information included is correct, complete, appropriate for the audience, appropriate for the purpose and acceptable for distribution. This is generally managed by a different person to the other types of review as it will often require knowledge of the topic being discussed.
This is extremely important as we might have a beautifully written piece with no grammatical or spelling errors that is completely wrong for its intended use, and does not convey the correct key message, or even worse contains incorrect information and misleads rather than educates. This is very well put in the book where it states:
If the message is incorrect, then the document fails, no matter how well the message is communicated or what form it is in.
I think this is something we all need to remember as we try to write or edit scientific literature.
