The key to citing any source is to:
- be consistent in style and format;
- have a clear and neat format;
- present sufficient information for a reader to identify and find the work or cited passage;
- not make up your own rules.
For citing material from the Web, two additional pieces of information are usually needed:
- the electronic address or URL of the site (e.g. http://...)
- the date you accessed the site or database
