Welcome to the library.
This is where you would normally read more about the topic on which you clicked. Notice the format of this page. At the top of the page there is the heading "Library" which lets you know that you are reading a library reference. Following that heading is the red term about which you are reading (in this case it was just a "test click"). Then comes the information on the term which you are reading now. Finally, at the bottom of the page is a navigation area that can take you to the library index, or any of the three models which you will be using. These links are not active right now, but they will be when it is appropriate.
In order to get back to the page that you were just on, click on your browser's left or back arrow at the top of the window.
