This website is about lists: lists of items that are web pages of one kind or another. These lists are prepared for you by website custodians, including Contributors, Authors, Editors, and Administrators. The main types of lists are topics (a list of any types of items), and folders (a list of external materials).
The idea is to lead you through a topic or folder by letting you browse through the items in turn.
An item in a list can be
Lists can be easily browsed, and the items in a list can be put in some order, to tell a story or lead you through a complex topic.
Custodians can create new lists from existing items, without disturbing existing lists. So an item can be in more than one list.
Topics (lists of items) can have a cover page to explain the topic. When the cover page exists it shows up as a "Cover page" tab. In that case, click on the "Content page" tab to see the list of items associated with that topic.
When you click on an item in a topic list, you go to a page view of that item, and you get a navigator at the top of the page view, which tells you where you are in your list of topic items. The navigator lets you flip to full page views of the next or previous items of that topic. If you see a navigator, you're on a list.
So to use this website, find a topic that interests you, and flip through its items!
You can read a Topic like a chapter in a book, or like a background file, depending on how it is organized.
