In some circumstances, longer and more detailed text will be necessary to convey the same meaningful information that other visitors to the website can see. For example, a map showing the locations of neighborhood branches of a city library needs a tag with much more information in text format. In that instance, where the map conveys the locations of several facilities, add a “longdesc” tag that includes a text equivalent description of each location shown on the map – e.g., “City Center Library, 433 N. Main Street, located on North Main Street between 4th Avenue and 5th Avenue.”
On the legal side, ambiguity in the law and the speed at which technology and dependence on the Internet has developed created an opportunity for litigation all over our nation. As these cases have moved through our system, the courts have been nearly split -- with the 1st, 3rd and 7th Circuits ruling that the ADA does apply to websites, while the 6th, 9th and 11th Circuits have ruled that it does not. These latter rulings have all been based on the interpretation that the ADA is focused on physical location and requires a nexus test. Other circuit courts in the United States have yet to rule on the topic.
