Greatest books - what's your tally?

Via Peter Martin's blog, this intriguing word cloud by Information Is Beautiful of the most mentioned and borrowed 100 books.

So how many of your favourite reads can you spot? Wouldn't be hard to trump my list:

• One flew over the cuckoo's nest
• Lord of the rings (does that count as three?
• The hobbit
• Hitchhikers guide to the galaxy (again, does that trilogy count as four?)
• To kill a mockingbird (who didn't have to read that one at school?)
• Great expectations
• For whom the bell tolls (a torrid read)
• Catch 22 (does it count if you managed to get 50 pages in before giving up?)

I guess the book snobs have little regard for sci fi...
