I had a discussion about this with my supervisor recently. What do you do if you have an abbreviation, such as etc. at the end of a sentence, or if you want to follow it by a comma? They say only put the one full stop so it goes...etc. or ...etc, not a full stop to indicate it is an abbreviation and then another full stop or a comma. They said this is convention. Is that so? Both look a bit strange.
Also, Harvard referencing. Do you write Changing job boundaries and workforce reform or Changing Job Boundaries and Workforce Reform some say do it the first way, some say the other way at this rate I will be producing alternative versions of my ref list!
