To help bring some order to this mess, we are beginning to put a few items at the bottom of each page to help the reader know more about the source of the data they are reading, the age of it, who is responsible for the page, and the "official URL" of the page.
OK, so the question remains. What is an official URL? Well, it goes like this. There is nothing more frustrating in life (besides perhaps the 5 minute red light near Stanton campus), than making a link to a page which disappears. The official URL indicates the URL that we will try to maintain. In other words, the URL or link you used to reach a particular page may change, but the official URL will hopefully not. Therefore, if you want to make a bookmark or link to a page, select the official URL and then link to that instead.
Ah, so what does URL stand for?! Uniform Resource Locater.
