Six of these thirteen novels/short story collections could be comfortably classed as children's stories. Except for David Copperfield, they are all relatively short--relative, that is, to the Victorian triple-decker, although a number of them are just short, period. With five novels in the top 100, Dickens clearly runs the Victorian roost.
Where are the other heavy-hitters of Victorian fiction, then? Thomas Hardy first appears with Tess of the D'Urbervilles (#112); George Eliot with Silas Marner--which, I've got to say, is absolutely deadly if you're trying to introduce anyone to Eliot's work (#159); Oscar Wilde with The Picture of Dorian Gray (#172). Poor W. M. Thackeray finally gets his say in with Vanity Fair, which is at #373. But he's doing better than Anthony Trollope, stuck in #500 with Barchester Towers.
Is anybody reading Victorian poetry these days? Lord Tennyson's Idylls of the King squeaks by (#584). Elizabeth Barrett Browning's Sonnets from the Portuguese appears much further down (#854)--but at least she's on the list, which is more than her husband can say. No Arnold, no Swinburne, no Rossetti (either one).
