On the plus side though, there's still Anne of, Little Women and Ballet Shoes for the GO genre. Plus books like Huckleberry Finn, Charlotte's Web, The Family from One End Street, all four books in the "weird and wonderful" category, Journey to the Centre of the Earth and Treasure Island for similar era books. And all the Roald Dahl ones, Anne Frank, Charlotte's Web, The Very Hungry Caterpillar (
), Peepo (
), The Hound
of the Baskervilles, Milly-Molly-Mandy, The Worst Witch (school story of a
sort?), The Sheep-Pig, The Borrowers, Goodnight Mr Tom, Carrie's War, Stig
of the Dump, Please Mrs Butler, and Michael Rosen's poetry, which have all
been around for at least 20 years as they all bring back fond, cosy
memories for me. Oh, and Earthsea, though I can't say I'd have considered
it a classic. I expect I've missed a couple more old ones as well.
See? I don't think we're all that hopelessly out of date, Twilight aside.
I am amused
by the category of "Phizzwizzers," which looks a lot like someone decided
they needed more Roald Dahl books on the list but couldn't figure out
where to put them! 
It does seem odd
not to see a single Enid Blyton on the list though, or any pony books for
that matter. I'm sure there were loads around 10 or 15 years ago. Do
little girls not go through the pony phase any more?
