A Web site that remains live but is no longer updated or maintained or only done so very infrequently. Unlike a site that is no longer available and results in a 404 error message when the user tries to access it, ghost sites can be accessed even though they have not been updated. Web sites typically strive for relevant information that is timely and current. However, there are some sites in which the content will never or rarely change, so there is no need to update the site. For example, a Web site that contains only the full text of the Declaration of Independence does not need to be updated as that data is never going to change.
