what about if it is a website? Is it the date i first visited that website?
Yes, although the date I'd record is the date I actually studied the site and took notes. In other words, you might bookmark several sites one day -- and actually read them carefully several days later -- discarding the sites that weren't useful to you. Use the date that you actually read and decide to use the site.
