Many of the documents on this site are in HTML or ASCII (plain text) formats. These formats are generally accessible to people who use screen readers. We also have a large number of documents in Adobe Acrobat® Portable Document Format (PDF).
PDF format is used to preserve the content and layout of our hard copy publications. Publications in PDF can only be viewed and printed using the Adobe Acrobat Reader®, version 6.0 or higher. You can download and get help using the Acrobat Reader at the Adobe Systems, Inc. site. The downloadable Acrobat Reader software is available at NO CHARGE from Adobe.
People using screen-reading devices generally are unable to read documents directly in PDF format, unless they have an accessibility plug-in installed on their system along with the Adobe Acrobat Reader. This plug-in is available at NO CHARGE from Adobe. Adobe also has online tools that will convert PDF files to HTML on request. To get the plug-in and latest news about Adobe’s accessibility tools and services, visit the Access Adobe site.
