Do you find it difficult to keep track of all of your references? Reference Manager softwares are designed to collate your references and make the writing up process easier. If you want to use a reference manager, it's worth starting now so you save time at the end. 

Jill is a Mendeley Advisor and so has put together a short demonstration of the Mendeley Reference Manager, a freely available reference manager which is available at: www.mendeley.com

You don't have to use Mendeley (or any reference manager), and you'll be able to find a comparison of reference managers here, but Jill is a very big fan of Mendeley and couldn't resist showing it off.
