Most computer systems from the past 10 years or so can use Acrobat Reader, which is available for free.  We try to create PDF files which will work even on older systems, but for best results, be sure that you have the most current version of Acrobat Reader for your computer.  (Check once a year or so to see if there is a new version.)

Many web browsers launch Acrobat Reader inside the browser and open the PDF file like a web page.  If you have an older system, you may encounter blank pages or other issues with this method.  If this problem occurs, right-click on the link to the PDF file instead, choose “Save Link As” to download the file to your desktop, and the open the file from there.  This will launch Acrobat Reader separately and should avoid the blank pages.

If you can’t get a copy of Acrobat Reader for your system, or you have other problems with our PDF files, send us your address and we’ll get the files to you in another form.
