From Jodi Kantor's article "The Literary Critic's Shelf of Shame":

In his novel Changing Places, David Lodge describes a literary parlor game called "Humiliations" in which participants confess, one by one, titles of books they've never read. The genius of the game is that each player gains a point for each fellow player who's read the book--in other words, the more accomplished the reader, the lower his or her score. Lodge's winner is an American professor who, in a rousing display of one-downmanship, finally announces that he's never read Hamlet.

The specter of Books Not Read haunts just about everyone I know who is an avid reader. For graduate students and professors in English, it's not uncommon for that specter to become a full-blown pathology: it is the Mr. Hyde to their Dr. Jekyll, the monster to their Victor Frankenstein, the Hulk to their David Banner. ("Don't make them tell you they 'didn't get to that'! You won't like them when they tell you they 'didn't get to that'!") It is the reason why so many academics feel like frauds. It is the reason why I hid under my covers the night before my doctoral qualifying exams and insistently told my husband that I wasn't going to go take those tests, and he couldn't make me. I went, of course, and was astonished to find that my professors somehow couldn't see the hulking beast of shame standing behind me.

But I think David Lodge has the right idea. That is why I'd like to invite you, gentle readers, to play a round of "Humiliations" with me. If you are one of those readers who is blessed with immunity to feelings of guilt about matters of reading--or not reading--then just pretend that the game is called "On My Shelf." I'll start:

1) Vladimir Nabokov, Lolita -- I've mentioned this one before. My failure to read the book since then only makes this a more emphatic #1.
2) Fyodor Dostoevsky, Crime and Punishment -- And I'm sure I'd like this book, too.
3) Thomas Kyd, The Spanish Tragedy -- I know this probably won't be on many of your lists, but given my field of study, this omission is pretty much inexcusable.

Now you.
