website v. web page
"website" refers to a collection of web pages sharing a domain name or design.
"web page" refers to a single page within a website, or to a one-page site.
"home page" refers to a site's first or primary page.

URL
In listing website addresses in copy, always check the links before trimming prefixes from the URL. Some sites don't work without the www. If the URL does work without the "www," feel free to shorten the address.
For Emory's main site, it can be helpful to use "www.emory.edu" because "emory.edu" doesn't look like a web address to some readers (it also has a different meaning in a technical context -- it's actually Emory's domain, not just the web address).

www.emory.edu
The preferred url reference to the main Emory University site; "emory.edu," though commonly used, is technically incorrect.
