How to Read a PDF

Essays that I first posted after 1 Feb 2003 are posted only in Adobe Portable Document Format (PDF). Documents in PDF can be displayed in a webbrowser using the Adobe Acrobat Reader. Most recent computers have a webbrowser and Acrobat Reader already installed on the hard disk drive by the computer manufacturer. Users of older computers will need to go to the Adobe website and download a copy of Acrobat Reader, then install Acrobat Reader on the user's computer. Instructions are posted at the Adobe website.

If you use the Opera webbrowser, look here.

The early PDF files at my website are compatible with Adobe Acrobat version 3.0 and higher. Beginning in April 2011, I have been using stronger encryption, which requires at least version 5 of Acrobat.

Why PDF files?

Since I first began posting essays on the Internet in 1997, I have been bothered by several kinds of infringements of my copyrights:
There has been significant economic loss to me from the violation of my copyrights and my terms of service. In the year 2002, there were a total of 362,527 hits on my professional website. If just 2% of these hits had resulted in payment of a $4 royalty to me, I would have received $29,000.   Instead, I actually received a total of only $44 in copyright royalty payments during 2002.

This calculation of $29,000 in the previous paragraph ignores the royalties due to me when someone prints one copy from my website (i.e., one hit) and then reproduces that copy with a photocopy machine for further distribution to students or employees. I have no way of estimating how often such further distribution occurs, but occasional e-mails to me confess that it has happened.

In the year 2011, there were a total of 1,382,572 hits on my professional website. If just 1% of these hits had resulted in payment of a $4 royalty to me, I would have received $55,000. That royalty would have paid for my time and expenses to research and write between two and four new essays.   Instead, I actually received zero copyright royalty payments during 2011.

To stop these abuses of my copyrighted essays, all new essays that I post after 1 Feb 2003 will be posted at my website in Adobe Portable Document Format (PDF), with security features enabled to disable printing and to disable cut-and-paste from my essays.

The fact that my earlier essays remain on my websites in HTML format in no way condones the continuing violations of my copyrights and the continuing violations of my terms of service.

Disabling printing and disabling cut-and-paste is necessary to prevent both (1) businesses and attorneys from exploiting my unpaid work and (2) plagiarism.   The inconvenience to honest people who respect copyrights is akin to higher prices in stores to compensate for shoplifters and pilferers.
