Citing Sources- The OWL at Purdue

Hey everyone; I had a student ask about citing sources yesterday and I wasn't able to find a great book right off hand, and I wasn't on my home computer to show them the site I use EVERY TIME I write a paper! So, here's the site, The OWL at Purdue...the greatest site I've found to tell exactly how, in ANY situation, to cite sources it-text and on works-cited pages. http://owl.english.purdue.edu/owl/resource/557/02/
