This is a great, free citation maker with some helpful shortcuts.
For a web site, simply click the "Website" tab
and enter the URL (I like to cut and paste it to avoid typing
mistakes). It creates a pretty complete citation that you
can fill in with details if needed. You can cut and paste
the completed citation into your works cited. It includes
templates for a variety of sources, including databases,
digital images, interviews, etc.
