We use "URL-minder" (http://www.netmind.com/htm/url-minder.html) to
monitor our catalogued websites.  You can set it up to notify you of all
changes (ie when a new issue of serial is added, or any minor change is
made to the site) or be more specific and ask to be notified only when the
site changes addresses or disappears.
