Beware that unis can use one of a range of referencing styles and they can all have subtly different formatting. If you use an automated referencing tool, make sure that either it conforms to your uni's referencing style, or that the output can be easily manually edited to meet it. You could find yourself making work rather than saving it.
For example, my undergrad uni used Harvard referencing - but they had an in-house version which tweaked it. Finding software that produced Harvard style referencing was only half of the solution. I'm currently having to use a format which inserts full stops where I was initially taught they should never be. Drives me nuts.
With referencing, attention to detail and following uni instruction, are key.
