Books Read per Year

Apropos of last week's chart, I decided to look at how many books I read each year and what slice of them were by authors I'd never read before. Is it true I've read more in recent years? Is it true that I read more of the same authors earlier on than I do today? Let's see:

Indeed, my gut feeling appears largely to be true! The number of books has gone up--though it's descended again the last few years. And the books by authors I've never read has been the larger share in most recent years. But let's see how it works on a percentage basis each year.

Yep, this confirms, by percentage, what I had thought. The blue takes up less space overall in more recent years than it did in earlier ones.
