- All text on this site, including the menus, can be scaled up or down by the user. Most current browsers allow users to scale the text up or down using the scroll wheel of their mouse in conjunction with the Control key.
- This site uses print CSS to make it more page-friendly when printed. Navigation elements are removed, but the breadcrumb and footer are left in place for context. Colors are reduced to black and white. For more advanced browsers, the addresses of links are printed immediately following the link text, and many abbreviations and acronyms are extended in parentheses on the printed page as well.
