Document Types

Throughout the site, we have linked to various documents for information and resources. Some of the documents are in Microsoft Word format and others in Adobe PDF. For the most part, these documents will open in a new browser window.

get Adobe Acrobat readerFor the items in Adobe PDF format. You will need Adobe Reader installed on your computer to read the files. If you do not have Adobe Reader, you can download a copy of Adobe Reader from the Adobe web site.

You can download the documents to your hard drive by right clicking on the file name and choosing "save target as" from the menu.

Feel free to contact us if you would like any of these documents in an alternative format.

Standards compliance

  1. Most pages validate as XHTML 1.0 Transitional and our Cascading Style Sheets validate as CSS2.
  2. The pages comply with all guidelines of the W3 Web Content Accessibility Guidelines.
  3. We make an attempt to label tables with captions and summaries to allow screen readers to render the table intelligently.

Navigation aids

  1. The main content is after the navigation links in the source code. Therefore we created a "skip to navigation links" link (access key 0) to skip to the main content. This link is visible to screenreaders and to sighted users that tab through the web site.
  2. All pages have home and copyright links to aid navigation in text-only browsers and screen readers.
  3. We make an attempt to label tables with captions and summaries to allow screen readers to render the table intelligently.


  1. Whenever possible, links are written in a manner that will make sense when read out of context. Screen readers can extract the list of links on a page and allow the user to browse the list separately from the page.
  2. There are no "javascript:" pseudo-links. All links can be followed in any screen reader, even if scripting is turned off.
  3. There are no links that open new windows without warning.
  4. Many links have title attributes that describe the link in greater detail, unless the text of the link already fully describes the target (such as the headline of an article).


All content images used include descriptive ALT attributes. Purely decorative graphics include null ALT attributes.

Visual design

  1. This site uses cascading style sheets and div tags for visual layout. Even if your browser or browsing device does not support style sheets, the content of each page should still be readable.
  2. This site uses percentage font sizes, compatible with the user-specified "text size" option in visual browsers.
