the long and the short

I'm prejudiced against short books, but when a book overcomes that prejudice and I can see that it holds real value, I then appreciate that book all the more. Examples include Frankenstein by Mary Shelley, The Anxiety of Influence and A Map of Misreading by Harold Bloom. 

There's nothing like a book that is both really long and really good though, and there are a lot of examples of that - The Idiot and The Possessed by Fyodor Dostoevsky, War and Peace and Anna Karenina by Leo Tolstoy, Middlemarch and Daniel Deronda by George Eliot, David Copperfield, The Old Curiosity Shop, Martin Chuzzlewit, Dombey and Son and Little Dorrit by Charles Dickens, A House for Mr Biswas by V S Naipaul, A Fine Balance by Rohinton Mistry, to name a few.
