For new features, I have added an iPad version. If you access Citation Machine with an iPad, it automatically switches over to a different version (http://citationmachine.net/iPad) that has a more mobile type of look and feel. The percentage of hits from mobile devices is still quite low, but with so many schools purchasing iPads for students, I suspect that more will be creating citations from their tablets. We’ll see.
I would like to add that I had to teach myself a lot in order to implement these changes, involving some deep researching of my own. I am reminded every day that to function in this day and time, we must all be master learners.
