There are many different "styles" for citing references, whether in electronic or print format. The "styles" are usually set by professional organisations and publishers.

If you wish to cite an internet resource, follow the format below showing the APA (American Psychological Association) style for citing general internet resources.

GENERAL FORMAT:
Author's last name and initial (if known) (Year of last update). Title of work (if available). Retrieved month day, year, from source [ie. URL].
