Access at Adobe was created to help people with visual disabilities by converting Adobe Acrobat files to HTML files. If your browser does not accept them, you will need to reconfigure your browser or find another way to reach those sites. Legislation and session laws often contain text that is being added to the statutes or deleted from the statutes. States, in their printed documents, often show this by underscoring, italicizing, or striking through text. States may use brackets, plus and minus signs, or other methods of identifying the added and deleted text.
Some states have instructions or help files explaining the methods they use.
Some of the sites containing statutes and legislation are difficult to reach during the day. My guess is that popular commercial web sites may increase capacity to handle increases in traffic, but popular state government sites are less likely to do so. If a web server gets more traffic than it can handle, some people will not get through. Occasionally a web site may be inaccessible for hours or days at a time because of technical problems. If more than one source is listed for the information you need, you may want to try another source.
