It is amazing how quickly and easily manuscripts can become confused, especially with different versions of the same one. If you have more than one copy of a manuscript, make sure they are all well labelled and even dated to ensure mistakes will not happen. There would be nothing worse than sitting for hours, writing or editing, only to find that you have been working on the wrong version. I have a system which I find works quite well:
1. When adding the file name to your original manuscript, make sure you add the word ‘original’ into the title. And then put that copy away if its complete, keep it as a reference. It will also safeguard against any unexpected happenings. Make a new copy to work with and number and/or date it. (I prefer to number it).
