Now it’s a simple matter of using the “Add as PDF to iTunes” PDF Service in the PDF Adder collection to add the Reader-formatted page to iTunes’ Books category and from there sync to iBooks. Of course, I’ve been PDFing stuff like this from Safari for awhile, but hadn’t thought to try it with Safari Reader. Neat!

This version now works in Snow Leopard but QuickTime Player 7 must be installed–even if QuickTime Player X is also installed. QTPX does not (yet) have the AppleScript support to use this script. QTP7 can be installed from the “Optional Installs” folder on your Snow Leopard installation disc. It will be installed in your /Applications/Utilities/ folder.
