AND NO ONE HAS EVER READ THE WHOLE:

James Latham, editor of the University of Tulsa-based James Joyce Quarterly, recently described Ulysses as probably "the most purchased and least read book in the world," according to the Tulsa World.

Just how accurate is that description? We wanted to find out, if for no other reason than to ease the sheepishness some of us feel for not having read Ulysses. (I have only read Portrait of the Artist as a Young Man and "The Dead.")

You may have always suspected that your friend with the full collection of Penguin Classics was using those books primarily as interior decoration. This is fine, of course: The publishing industry needs all the help it can get--and Umberto Eco says a library filled with unread books is far more valuable.

Data suggests that many people indeed buy the works of Joyce and other high-brow literary authors for largely the same reason that Hansel from "Zoolander" admires Sting:

Sting would be another person who's a hero. The music he's created over the years, I don't really listen to it, but the fact that he's making it, I respect that.

Since detailed data and metrics have supplanting sales and subscriptions in publishing, the world of media has changed significantly to focus on what people read. As Vox's Todd VanDerWerff put it last year, "Newspapers could suspect nobody was reading the city council report or the dance review; with the internet, we know nobody is."

For books, however, data has been less forthcoming since most people cling to their metric-proof bits of wood pulp, thread, and glue. But not completely. Thanks to the Kindle and other e-readers, there is some data showing who has actually been reading. Amazon's devices communicate and sync with each other, through the company, revealing how many people downloaded a book, whether they read it, and how long it took.

Unfortunately, Amazon rarely (like never) shares its data. But there are other ways of telling whether your pedantic friend has actually made it through the Great Slogs--and I say this with love to the great books, many of which I have read. (Or have I?)

In 2014, University of Wisconsin-Madison Professor Jordan Ellenberg invented the so-called "Hawking Index," which uses Amazon e-book highlights data as a proxy for where people stop reading the books they've purchased. Some people use the highlight function on the devices and apps, and the unscientific-but-workable "Hawking Index" uses the assumption that if the most-highlighted passages are clustered at the beginning of the book, the book is more likely to have been abandoned. (The name refers to Stephen Hawking's A Brief History of Time, which is ranked up with Ulysses for the dubious title of "most unread book of all time.") On the other side, books with popular passages marked all the way to the end mean lots of people made it through the entire story.

So on this Bloomsday where does Ulysses truly stack up? Here's a list of famous books and their scores on the Hawking Index, ranked from most-likely abandoned to most likely-finished.
