I think we should have a bookshop, and I think it should be like Books Actually - except actually with books.
What I'd have (in addition to novels, I mean):
(1) A decent poetry section. Which means that twentieth-century poets cannot be limited to the collected poems of Yeats and Auden (separate collections, I mean).
(2) A decent non-fiction section. Why is it that Singaporean bookshops hardly ever carry non-academic non-fiction? Including personal essays, humour (I'm thinking of Thurber), travel, journalism with footnotes (I'm thinking of Eric Schlosser and Timothy Garton Ash), critical essays (I'm thinking of Northrop Frye's radio lectures? - The Education Imagination, and Anne Carson's wonderful book-length essays), political essays (but only if very good; can't think of an example), food, and so on. And some academic books (I'm thinking of Benedict Anderson).
(3) Children's books.
