For Lyrical Ballads, you should allow either Coleridge or Wordsworth. I typed one, then other, then "Wordsworth and Coleridge", and none worked... I also agree with Allbert that it would be better to feature each author once. Good to see poets though!
A good quiz - nicely challenging. But like previous commentators I'd prefer to see authors mentioned once. Leaves room for the inclusion of others who are noticeably absent. It's a shame, for instance, not to have included (hmm, let me see...) Hardy, Trollope, Wodehouse and Waugh.
