RefWorks is an online research management tool that will let you - amongst other things - generate citations and bibliographies.
The Bodleian Libraries has a subscription to RefWorks, so any member of the University can create an account.
N.B. If you want to access your account from outside the Oxford domain, you will need to input the Oxford "Group Code" before being presented with the RefWorks login page. You can access the Group Code here using your Oxford University SSO username and password.
The University has produced a short guide to what constitutes plagiarism, and how to avoid it: http://www.admin.ox.ac.uk/edc/goodpractice/about/
You can also find a useful annotated guide to some of the more common types of unoriginal work in this guide created by Turnitin:
