PC users:  there are some free PDF viewers that have annotation and highlight functionality.  For help using any of these applications, please consult the help/support links found on their websites.

Mac users:  use the built-in Preview application. Simply double click the PDF file on your computer (if you have another PDF viewer set as default, you will need to select the file, then click File > Open With > Preview).

  • To add text to a file, click Tools > Annotate > add Text.
  • To highlight, click  Tools > Annotate > Highlight Text

Mobile device users:  look in your device's app store for applications that will allow you to annotate PDF files.  See examples for iPad and Kindle Fire.
