Up until FET inputs on op-amps, ALL op-amps were current input devices. Using resistors in various feedback schemes they are made to act as voltage input devices.

Check to be sure that you are using the latest Acrobat Reader version, and maybe see if any of your other friends can read it okay. Otherwise, just use the original google search to look for similar write-ups. The TI on is especially good though.
