The diagram below shows the structure of the site. There are seven “buttons” on the navigation bar shown on the home page at the top of this diagram. Clicking on one will take you to a “List” page (first row in the diagram). Clicking on one of the links on that page will take you to a “Subject” page (second row). Clicking on the subject of an article will take you to an abstract (third row).
