NoodleTools is an online tool that helps you create citations and reference lists step-by-step. Try it, you'll like it!
The CSM Librarians created detailed guides on how to cite.
Compare citing to "assist" in soccer (or another sport): record is kept (statistics) and rewards follow (recognition, remuneration..)
See a couple of short videos on the subject of citing:

Additional guides with examples.
A reminder: CSM library databases contain citations to all the articles available there...just look for the "cite" or "email" on the search results pages!
