Here's a cut-down version of the Referencing and Plagiarism presentation that I'm currently delivering to classes around Newcastle College. It explains all about Author-Date Citations and Reference Lists/Bibliographies, features some worked examples and contains at least two dreadful jokes.
If you think it would be useful for me to come and do the full version of this presentation with your class, please tell your tutor to drop me an email. Alternatively, if you are having trouble with referencing, then feel free to get in touch with me yourself. My contact details are at the foot of this blog.
