In addition to his blog Duff has published dozens of articles since the late 1990s to help educate IT executives, CIOs, developers and others on PDF, accessibility and electronic document technology. This page includes links to most of Duff’s feature-length articles in approximate chronological order, with the newest at the top.
Most of the older articles are now maintained on TalkingPDF.org. Others were posted to the PDF Association website, and may not be linked from here.
Other unsolicited advice and occasional rants may be found throughout the Planet PDF archives, Adobe’s User to User forums and AcrobatUsers.com.
