a rare and unusual psychosis

I'm sure there were plenty of people who felt that turning pages just wasn't the right way to do things; rolling the scroll was an essential part of the reading experience. And let's not forget those who were of the firm opinion that one couldn't get the true value of a story unless it was being told by a trained bard. Looking at all those silly squiggles on a piece of parchment couldn't possibly recreate the experience properly.

So, no, it's a very common and unusual psychosis.
