The two books on the list I haven't read,
Clarissa and
White Teeth, turned out to be the least read overall. I doubt I'll ever read Clarissa as it's so long, but I'm currently reading a book of essays by Zadie Smith to try to close that particular gap.
I'm quite surprised by two other books that got little love.
The Golden Notebook was something of a required text for those of a feminist bent in my salad days and
The Good Soldier probably makes my top-three novels list.
No real surprise that
Nineteen Eighty-four is the most popular. It's accessible and has the effect of making people feel as if they're smarter than they really are.

I always thought it overrated and then discovered recently in a book club read that Orwell had ripped off an earlier Russian novel,
We by Eugene Zamiatin. I think Orwell's non-fiction is wonderful and I like some of his less popular novels; I'm just not that fond of his two biggies.
