The definition of a website is a page or collection of pages on the World Wide Web that contains specific information which was all provided by one person or entity and traces back to a common Uniform Resource Locator (URL).
A set of interconnected webpages, usually including a homepage, generally located on the same server, and prepared and maintained as a collection of information by a person, group, or organization.
Usage Note: The transition from World Wide Web site to Web site to website as a single uncapitalized word mirrors the development of other technological expressions which have tended to take unhyphenated forms as they become more familiar. Thus email is gaining ground over the forms E-mail and e-mail, especially in texts that are more technologically oriented. Similarly, there is an increasing preference for closed forms like homepage, online, and printout.
