Discussion and Articles
Many experts still believe PDF cannot be made fully accessible to users of assistive technology. Included below is a selection of articles and guides exploring the advancements and barriers in the efforts toward making accessible PDF a wide-spread and user-friendly reality.
The Accessibility of Adobe™ Acrobat™Software for People with Disabilities. -- American Foundation for the Blind. 2004. Summary: "Adobe's suite of Acrobat™ software products enables users to create, format, and read Portable Document Format (PDF) files from a variety of applications. PDF files are an industry standard for sharing richly formatted documents. More than 20 million documents are available using this format on the World Wide Web, with more than two million on government web sites. Corporations and institutions, across industries, compose and disseminate everything from user manuals to annual reports to legal documents using the PDF file format. To assure the accessibility of Acrobat™ software for disabled users, Adobe Systems Incorporated engaged AccessWorld Solutions (AWS), the consulting arm of the American Foundation for the Blind. The purpose was to evaluate the accessibility features of Acrobat™ 6.0 and Adobe Reader™ 6.0 software products and provide recommendations for making PDF files more accessible to people with disabilities. This paper summarizes the results of that evaluation and discusses how the results contributed to improving the accessibility features of Acrobat™ 6.01 software."

Adobe Acrobat Accessibility Techniques. – WebAIM, Techniques and Concepts. Conclusions: "It's wonderful that Adobe has made it possible to make PDF files that are accessible to users of screen readers. Acrobat 6.0 takes a huge leap forward, by embedding a text-to-speech synthesizer in the Reader itself. Still, you can't count on users having the right combination of software and expertise to make use of the Reader's extra functionality. It's always a good idea to provide an HTML version in addition to the PDF, even if the PDF is created with accessibility in mind. Acrobat PDF files can be made directly accessible to users of the JAWS and Window Eyes screen readers, but no other screen reader yet supports the ability to read PDF files directly."

Adobe Tackles Software Accessibility Issues . - American Foundation for the Blind. 2004. Conclusion: "Despite the many improvements that have been made, Acrobat 6.0.1TM and PDF files are still not perfectly accessible. Some problems may never be totally resolved, since many PDF documents were created several years ago on previous versions of AcrobatTM that lacked accessibility features. However, Adobe is committed to resolving all outstanding accessibility issues that are technically possible to fix." Online at: www.afb.org/Section.asp?DocumentID=2331&Mode=Print.
PDF format is still not fully accessible. – 2003 Monash Web Workshop Series, Monash University. Summary: "Although there have been significant improvements to the accessibility of PDF documents, they can only be accessed by blind users in a very limited set of conditions. As a result, whenever PDF documents are used on the web, they should always be supplemented by an accessible alternative (in HTML, RTF, or text format)."

PDF and Public Documents: A White Paper. -- American Foundation for the Blind. 25 April 2002. Conclusions: "While we applaud Adobe's efforts to make Portable Document Format (PDF) more accessible, the limitations of existing practices and technological capabilities available to end-users who are blind or otherwise print disabled render documents and forms in PDF inaccessible to many members of the public. This white paper explains the problems that surround the use of PDF documents and forms in light of the section 508 standards and draws the conclusion that alternative, accessible formats must always accompany PDF versions of information and data that are made available to the public."

Strategies for PDF Accessibility. – Duff Johnson, Planet PDF. 20 February 2003. Summary: "Adobe's Current Strategy (as described on access.adobe.com): enhance the PDF format with MSAA-aware capabilities (tags) that document developers may use to improve accessibility. This approach is rooted in the belief that accessibility is operationally defined as the ability to interact with the user's choice of screen reader software. Usability is not part of this definition." Online at: www.planetpdf.com/mainpage.asp?webpageid=2578.
