To fulfill the objectives of our accessibility commitment, we have adopted as our primary guidelines the Section 508 Web site accessibility standards set forth in December 2000 by the Access Board, an independent Federal agency devoted to accessibility for people with disabilities. We continuously test our Britannica Online Web sites for compliance with the accessibility standards set forth above. The accessibility of Britannica Online Web sites, however, depends on third party technologies provided by operating system, hardware platforms and assistive technologies, all of which can affect the level of accessibility of Britannica Online Web sites. In order to continuously test our level of accessibility, our team of developers utilizes a software program called Bobby Worldwide developed by the nonprofit Center for Applied Special Technology (CAST). To ensure the accessibility of the Web site in the library, we also consult with members of the disabled community on a regular basis. We will continue to enhance the accessibility of our online products as greater functionality becomes available to ensure ongoing usefulness to all users, including those with disabilities.

We also are committed to addressing issues that prevent the use of our software by people with disabilities. We welcome your feedback and suggestions. If you have any comments or questions about our online products and the accessibility thereof, please contact Britannica Customer Support.

In addition, please let us know if you have any problems accessing our Britannica Online Web sites. When you contact us, please provide the following information:

• The nature of your accessibility problem.
• The format you prefer for receiving requested Web site material.
• The Web address of the requested material.
• Your contact information.
